Zebra Fish Experiment
Zebra Fish Experiment
I
bought the zebra fish with an intention of crossbreeding them.
They are
easy to breed but one need an elaborate tanks to separate the eggs from
the parents and also have adequate quantity of infusoria.
Infusoria
Infusoria
grows naturally in most tanks, particularly those with live plants.
However, there may not be sufficient quantities to sustain a full
hatching of fry.
The term infusoria is an old one that has changed
in meaning over the years.
At one time it referred to just about any
microscopic, or nearly microscopic, organism that lived in fresh water.
That use of that word long ago became outdated in the scientific
community.
However, the term infusoria is still used by many within
the aquarium community, even by younger fish enthusiasts. To aquarium
enthusiasts infusoria refers to many small organisms in water that tiny
fry can feed up upon.
Although it's not feasible to name every
organism that could be in an infusoria culture, some of the primary ones
include, algae (volvox), amoebae, euglena, paramecium, rotifers,
stentor and vorticella.
Therefore, it is helpful to culture your own infusoria to ensure having an adequate amount.
Zebra Fish Breeding
Nature has lot of surprises for you and me.
I was trying to raise a Guppy fish with swordtail for ages.
It was easy in good old days when the brood was wild.
They did not have the present sailtail (Sary Guppy) then.
But with the breeding of exotic and the emergence of the sail-tail or sari-tail varieties of guppies one cannot find guppies with the narrow short dorsal end of the tail with a broader and longer ventral end.
I have been screening the tails of guppies and found one with the suggestion of a swordtail and I mixed that one with the wild (not really wild) looking with light featured female guppies but there is no success yet.
They breed less in the glass tanks.
I am waiting for a miracle to happen.
But
toady, I was doing my daily routine of mixing different batches of
guppies to interbreed and quite casually looked at the fortuitous zebra
breeding tank to see whether the water quality was OK.
This plastic kitchen sink type of container
was designed to put zebras to lay eggs and in my opinion it was not
ready yet to put the adults. But as a conditioning routine I load it
with the first portion of outlet water bucket from my main tank with
zebras. Idea was to build the infusoria for the young ones, if they lay
eggs by any chance. These eggs are very small and not visible to the
naked eye. Most of it is eaten by the adult males and adult males are
necessary for the fertilization of eggs.
They lay over 400 to 1000 eggs but rarely a few survives in the tank.
By
removing water at the bottom by siphoning, I expect few eggs by chance
to remain trapped with fortuitous black fungus (which appear like a tuft
of leaves when fully grown).
Fish do not eat this black fungus probably it has nasty taste or alelopathic chemical.
Then in the main tank to clown fish do the cleaning up of the eggs no sooner they are laid.
I have been doing this religiously for the last one year but without any luck.
My first batch of zebra (breeding) was discovered accidentally in a bucket with water plants left to nature.
I had about 20 odd young ones and introduced 16 to the main tank leaving behind only four in the original bucket.
That was a shear intelligent decision the ones introduced to the tank (fairly big) were eaten by the adult in one night.
They are very good at population control of their kind.
I wonder how they survive in the nature.
Probably the adult die soon after breeding with endemic parasitic diseases.
To
my surprise there were six young one in the plastic container that
survived the natural population control. Now I cannot put siphoned water
to this tank for at least six months since they (young zebras) will eat
all the eggs.
I have to leave them in series of buckets and I have no room in my rooftop garden for any more buckets. So my zebra breeding will have to be done on makeshift containers. I cannot put the six young zebra fish to the main tank with zebras (they will be eaten) or to the other tank with live bearers.
Young zebras will eat all the live-bearers’ young ones.
It is a paradox and reproducing nature is only an ad hoc experiment.
In
a different note, I have a fabricated rainfall detector (modified fish
tank) and it recorded half an inch of rain for the last one week.
That I think is 25% of the usual rainfall and my predictions are we will have a drought by next April.
Albino Tetras
Albino Tetras
Toady, I received a batch of albino tetras free of charge from a dealer, whom I knew for two decades.
The idea was for me to look after them (confirmed disabled) sympathetically until they die.
One of them died on transit due to shock.
Rest went into panic state the moment, I introduced them to my main tank.
I sat there and watched their agony for half an hour.
Only two recovered in half an hour.
Most of them were partially blind or an eye was totally missing.
One was totally blind and took the longest to recover.
After one hour all of them could balance and swim in a comical manner.
They had two problems.
One was blindness.
The other was balancing.
I believe these strains are poisoned in their breeding.
They must be using very toxic material.
There is unsupervised breeding programs in this country.
These chemical are hazardous to humans and other animals and are slowly percolating into our ground water.
Who is allowing these materials to be imported?
That is my big question.
Zebra Fish and Black Guppy
Zebra Fish and Black Guppy
I have reason to believe there is unhealthy practices of Fish Breeding.
I may have briefly mentioned this sometime in the past.
I cannot trace the piece of writing.
In any case there seems to be new developments.
There is a guy who breeds albino zebras.
He has now introduced a pink strain.
I have an obsession on the topic of pigmentation, especially in regard to Guppy fish.
I wished as a kid, I could see a Guppy black like a black molly.
A guy in Thibirigasya, actually accomplished it.
He deserves a Nobel Prize.
I do not know how he accomplished it but to see a Guppy with band of black is common now.
These Guppies are robust, healthy and of reasonable size.
But all the variants of Zebras were tiny.
They do not grow to adult size in spite of proper feeding.
They do not mix in the shoal with normally colored zebras.
In other words they were unhealthy.
Goby Fish
Goby Fish
Goby fish is an ugly fish.
Small in size similar to Guppy fish but live in both fresh and sea water.
I have not seen one live. They type that live in mangroves slide into tunnels made by crabs on mangrove roots with the sliding tides. There are tiny octopuses who feed on these fish.
The ecosystems in mangroves is unique. Our mangroves in the Negamboo, Ceylon is fast receding.
Blind Fish
Blind Fish
I volunteered to look after a batch of blind and partially blind fish.
After nearly 20 months only three are left.
One has total visually capacity now.
One is blind in one eye.
The other is totally blind.
It amazes me how it survived.
It more amazing how it detects me.
The moment I sit next to the tank it comes near to the side my chair is kept.
The blind fish knows I am there.
I do not touch anything.
Probably it detects my foot steps and pulling the chair (gently).
I do not feed that tank (to confuse the blind fish in a way) first as a routine but feed the fish in the main big tank.
Moment
I start putting the pellets that sink to the bottom, the two clown fish
make a mess of the bottom sediment, and then the blind fish hits at the
bottom or the floor in a random fashion and finds its food.
That's how it survived.
I believe the other fish, especially the clown fish (scavenger) gives a subsonic message to the blind fish.
They are all in one community.
Guppy Fish
Guppy Fish
I have a life long relationship with Guppy Fish.
Guppy Disease
Guppy Disease
But one cannot have a pond without fish.
Just to introduce some colours I bought a batch of bright coloured guppies.
I added few of my wild guppy to interbreed.
In no time one by one all the guppies started dying.
Not other fish types.
I made sure there was no contact or contamination.
Within 24 hours they show the signs of disease and start dying.
If you buy a new stock do not introduce them to your main tank.
Treat them if necessary and introduce only the healthy ones.
Ideally the next generation of young fish.
If they are healthy they breed and breed fast.
My Fish with Scoliosis
My Fish with Scoliosis
Even though the life started in water, unlike terrestrial organisms they are at tremendous odds.
They never sleep.
They have to be under constant vigilance.
Out of 11 four are still living.
Most of them died due to poor water quality.
Once I improved the water quality they adapted well.
Strangely, they instantly sense my presence near the tank.
How they do that I do not know.
Coming back to the fish with scoliosis it makes a tremendous effort to swim if not float.
It is an ugly sight to see it swim but when tired rests on top of the air pump.
I put some floating plants so that it can rest and have the benefit of oxygen at day time.
Funny part is other fish also take advantage of the plant nest.
It is a cool resting place for them.

Old Cricketers of CEYLON
Old Cricketers Except D.S, the undesirable
This bit is a "gossip", I made to a local paper.
I do hesitate to write anything about present cricketers except Mahela (not necessary for Sanga, with a big wag) for posterity.
They are our Rohan Kanhai and Kallicharan duo.
There is no one who looks like Vivian Richards on record in Ceylon.
Cricketers (all good cricketers should do that) used to walk away (like Mahela) if they felt they were out without leaving the agony for the umpires to guess.
Our cricket Board is corrupt to the core like our politicians.
Politicians
(even after heroic victory) and board officials (big mess in cricket stadiums - the grass they used to overlay to cover the corrupt practices- milking every benefit possible) never resign.
1. Kehel I knew him well in cricket and police.
2. Daya (Sahabandu) used to ball SIX different ways in an over.
He was the worst fielder we ever had.
He (probably) never caught and balled a victimn in an international.
Somebody had to be in the Circle or Ring to catch for him.
It was very nice cricket anyway, without a hype.
3. We had a guy called Ben Navaratne who whipped the bail by his tongue and the umpire could not catch the trick.
If
he became a politician with his wagging tongue (not the tails of
present parliamentarians), God only knows, how high he would have gone up.
4. Micheal Tissera was the best we had, he could have achieved more, if not for the fact, his buddy (best man) eloped with his wife to Australia.
Collection of these writings should be there in the Web, preserved as archives, for the young ones to browse.

Origin of Zero as a Concept
Naturally CEYLON TEA-Positivi-TEA
This is about CEYLON TEA, the best Tea in this World which Queen Elizabeth enjoyed and endorsed.
I am not sure of the stance of King Charles III.
I decided to Go Zero Digitally (No Internet) last December but found it a daunting task having been an Internet Addict for over 15 years.
Blog activity was natural transition and I made it a point to “post unedited pieces to my friends” via emails expecting them to make some comments.
Feedback was good 10 years ago but it started declining when I took politics, religion and science by the head and tail and started questioning the rigid dogmas.
Mind YOU my original idea was to promote Linux and the site's name is Linux 100.
When I realized only 1% of the population use Linux (most of them were most likely / probably were more advanced than me in Linux environment), I slanted my activity to politics and last of all to satire.
I believe a lot did not like that change of character.
People want to hear one or their side of the way of thinking.
“Yes Men” mentality of politicians is an antithesis to my liking.
There is no alternative to “Thinking to Think” or “lateral thinking” of Professor De Bono’s philosophy.
My last post denounced all the institutions of rigidity as a preparation to “Go Digitally Zero”.
You may not hear from me (I am hibernating digitally) in the year 2017.
That does not mean I am dead and gone and my email is censored.
It only means I am in full retirement (Internet wise) gear.
Real reason is when (I am not a criminal, an ordinary guy) I realized, CIA, KGB, FBI, NSA, MI5 are snoozing on everybody’s (not only mine) email and social media activity, one is becoming a part of that clandestine scheme is not at all healthy for my soul.
If Internet is for the Secret Service I do not want to be a part of it.
I prefer a “Virtual Cloud” and my clientele is not big enough for such an activity.
My guess is millions of ordinary well versed people will join me in no time and would device alternative channels for communication (The Big Companies have already done it or are setting up their "Virtual Worlds”).
Read the content below which is 5 years OLD.
It has not improved but declined in quality and spirit.
A comment I copied from New York Times, 5 years ago.
My writing by accident coincided by good grace!
In the course of the volume the Internet is characterized as a cesspool, a porn store, a form of pinkeye, a raunchy fraternity, a graffiti–filled bathroom wall, a haven for sociopaths, and the breeder of online mobs who are no better than “masked Klan members” in their determination to “interfere with victims’ basic rights.”
Start with a little citation from Scientific American (Freedom in 2011 as opposed to 10,000 years back in evolution)
Big Caveat:
More freedom does not necessarily equal more happiness.
In fact, more choices may mean more confusion, mistakes, regret, even despair.
That is the irony at the heart of Jonathan Franzen’s latest novel Freedom (Farrar, Strauss and Giroux, 2010).
I need to be brief in this essay.
If I do it as a lengthy academic or scientific exercise this piece has little currency in today’s world.
Yes you have the freedom to browse but how do you set about it in the first place?
One must ask a few questions from oneself before the click happy (instead of the trigger happy old world) finger of yours takes over your senses or in this current year 2011, your touch happy finger dictates your impulses.
Why I am browsing?
The list can be in the hundreds but one must chop it down to 3 or 4.
1. Is it for inspiration (that is my first choice)?
2. Is it for game (occupy the free time you have in a constructive and enjoyable way)?
3. Is it the reflex action (routine) you have become a slave of?
Let me explain my first choice for clarity.
We are a country which is emerging from a bitter conflict of prehistoric value and still have not got rid of the ancient and vibrant hate philosophy (my creation of a concept – how hate operates and perpetuates hate into all spheres of activity and faculties) and failed to be actively engaged in this present moment of welcome freedom (all sides to the conflict are to be blamed) constructively.
So as an escape mechanism to avoid internalization of the conflict and forgive and forget philosophy to take root, I used the Internet constructively to promote Linux (Live CDs mainly).
Then I scanned the statistics to see only 1% used Linux (it is less than one 1% in this country) in the year 2010.
Can this 1% have an impact in changing world?
The answer I leave it open for the time being and I want to raise this question again few years later.
I put my experience first.
The one 1% of Linux enthusiast contributed more than I wished for in the year 2010.
At the year end, I was very happy I had ample time to explore new frontiers.
Writing of this piece is a valid endorsement of that fact.
I am inspired in spite of the small percentage points in statistics.
So inspiration is a relative thing, the problem comes when one tries to assess it quantitatively instead of qualitative empowerment.
Even at worse of times, one can achieve the targets if the target is simple.
It is getting lengthy and I am off the target a bit but this preamble is necessary to summarize the plausible approach to resist the Internet's preoccupation and temptations.
One should have few questions set, before you press the finger on Enter button.
The questions should be relevant in age, time, place and person.
If the browsing habit does not give correct yes or no answers to the questions, set out in the first place, it is the onus of the free individual to resit the temptation and switch off the computer.
Without over reacting.
This is not easy.
This has to be done in early ages and in school.
I browsed somewhat restricted sites (Linux mainly and in this specialized area also there are hackers who invade one's privacy and install scripts to hack a system.
I have not found a single tool in the entire web world (except the advice to parents and users) that let a child or kid would not enter into deep water.
This can be accomplished in a game like manner when one is entering the underworld of Internet.
I have some devices thought about that would work on a child friendly and inspirational way.
This is not the place to write more about that but to state firmly that it can be done without much a do, if the adults are ready to take leadership in this arena.
But I should end up with a warning for adult over 55 years (let me say early retirees who are looking for part time jobs or some pre-occupations) they can be gullible target audience for insinuation and luring to porn sites.
They are waiting there for you to register at a site and with your e-account (can be used for blackmail ploy, if one is married or is engaged).
Some teenagers are using the same tactics to lure children and bully them, too.
If an adult get caught, I have no sympathy.
You ought to have been wiser but we should not let Internet destroy some of our unsuspecting kids who are using their natural instinct of exploration to expand their inner world.
I say we should actively develop mechanisms instead of dishing out only warning and advice.
