Experience with glowlight tetra fry?
Apparently we have The Love Tank. I've never had baby fish when I've had tanks before but our two-month-old tank is full of love.
The mollies were born April 6th and today we discovered eensy teensy little fry we're assuming belong to the glowlight tetras. We have four--I think three girls and one (studly) boy.
They are tiny and hard to see but we managed to get one and put him in the baby net we had for the mollies (who are now huge!).
There are more underneath the short grass we had gotten to help hide the mollie fry. Any experience with these guys? I'm an unfit mother, I admit. :oops: I kind of want to pull everything out of the tank (28-gallon) and hunt for the others but I don't want to disrupt any eggs.
Re: Experience with glowlight tetra fry?
It's a bit too late, but you needed to start an infusoria culture to feed to the glowlight fry. They are too tiny to take anything over microscopic life for at least 10 days before they can take baby brine shrimp. I've taken the liberty of reproducing a section of my how to culture manual so you know how to culture infusoria.
Infusoria is a general term for freshwater microscopic life that lives off vegetative decay. It is the Number One food to learn to culture if you want to raise egg-layer fry. The best organism to culture is Paramecium, as most all egg-layer fry instantly recognize it as a food source.
A clean container; tall like a drinking glass
A Paramecium starter culture.
Wheat grains and Brewer's Yeast tablets
Aluminum foil or clear wrap.
Air pump and stone.
Optional: A microscope capable of X50 magnification, or a really good magnifying glass.
Depending on the size of your culture, sprinkle enough wheat grains to cover half of the bottom of your culture vessel in one layer. Then tip them into a microwave-safe container, cover them with about an inch of water, and microwave them until the water boils. That serves to soften the grains a bit, and also kills any organisms already on the wheat.
Pour the grains and water back into your culture vessel. Break a yeast tablet in two, and toss in half. Then fill the vessel with cool dechlorinated water up to about an inch or so from the top. You'll want VERY slow bubbles from your air stone, just enough to break the surface tension but not enough to roil the water at all. Its there to keep the culture fresh and clean smelling.
Introduce your Paramecium culture, cover the top with the foil or clear wrap, and put it near a window where it'll get mostly indirect sunlight. The wrap or foil keeps the water from evaporating so quickly.
Room temperature, it takes a week to 10 days to get a rich culture. Warmer, around 80 degrees, it can take as little as four days. The culture will get more and more milky. When its difficult to see the other side of the container looking through it, the culture is ready. They'll be a slight scum on top, which is normal.
If you have access to a microscope, use an eye dropper, put a single drop on a glass slide, and dial in 50 times magnification. You should see the field full of the little slipper-shaped Paramecium zooming all over the place.
You can use a magnifying glass, but you'll have real trouble seeing the Paramecium with it. You'll likely only be able to see a few of the largest of the critters, which will look like very tiny moving dust.
Harvest them by dipping some out with an eye-dropper from below the scum layer, and squirt it near the fry. The number of 'squirts' per feeding depends on the number of fry.
A trick I learned years ago is to put a bare light bulb on one side of the fry tank. It serves to bring the fry and the Paramecium together.
You'll see the fry curl into a tiny 's' shape and strike at the Paramecium. Feeding them every hour and changing 50 percent of the tank water daily will result in 70 to 90 percent fry yields.
You should be able to keep your culture going for at least a month. You can help by adding just enough Phytoplankton (Euglena is best) to tint the water green, as the Paramecium can eat the algae.
When your culture starts to become clear, scrape off a little of the muck at the bottom of your culture along with a few wheat grains and start another one. They'll be enough Paramecium in the goop to get the new culture going.
If you have any questions or are confused by any of the terms just ask.
I just boil lettuce then put it in a small container with an airstone. in a few days with strong light you will have some food for the fry.
