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That use of that word long ago became outdated in the scientific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.
