Question 9 fry hatched - food? HELP

Nine tiny fry have hatched in the breeder net. They move around but mostly hide under the plastic frame of the breeder net. I am not sure what they can eat: I put a drop of liquid from the brine shrimp into the breeder net. Can they eat this and what else can they eat? They are so small that I know they will be eaten if I chance letting them into the main part of the tank but I don't want them to starve! Ideas please!!

I did put hose over the filter intake in case any others hatch. No wonder I have only had 1 or 2 survive when I let them hatch in the tank on their own.

i would think you could take some flake food and crush it up real fine, almost into powder and feed that to them.

I take it you have no liquid fry food. Since it's sunday night and stores are closin, as an emergency you could try wetting falke food then see if they can get some.if you feed liquid food wouldn't ity just pass thru the net.Guess you'll need a grow out tank/bucket i'd probably rig something up w/o2 and a heater. If its a small amt of water it would be easy to keep the water clean i.e. no fitler. Could it work ? or are cories a seneitive fish ?Cuz i think you'll have to feed infus_ium.Then after a week or so, when they can eat brine shrimp or flake (soaked) you can return them to the net. IDK but i'd probably try to save my babies.

I remember reading about using egg yolk as fry food. Of course I doubt I'll ever have fry so I didn't pay attention to the article. There must be a recipe on google somewhere...

Found it:

Egg infusion is another time honored method of feeding very small fry. It used to be very common in stores, being sold under the name Liqui-fry as a first food for fry. I don't see that stuff around much anymore, but that's OK because it's real easy to make for your self. All you do is hard boil an ordinary chicken egg. Once it has cooled, you remove the shell and the white (you can eat the white if you like) leaving just the yolk. Put the yolk into a sealable container along with a volume of water about equal to that of the egg yolk. You may want to mash up the yolk with a fork a little bit before the next step which is to seal the container and shake it for all you're worth. Others may want to use a blender or a food processor, but either way you get a suspension of very fine particles of egg yolk. As mentioned above, this can be used to help along the infusoria culture in the spawning tank, but it can also be used to feed the fry.

If you don't stand up for something you'll fall for anything...

Ok, tried the boiled egg yolk dissolved in water. I mushed the egg yolk into tank water, just a small amount in a plastic baggy. It diffuses very quickly. I turned off the filter and poured some in the net. I am not sure how to tell if the fry have yolk sacks attached still or are "free swimming". A couple can go up and down the side of the net, the rest hide under the plastic frame of the breeder net.

I noticed the neons run up to the bottom of the net when I pour the egg yolk in so I tried putting a canopy plant under the net. The fry move around more with the added cover. Pour babies - it must be like a surfer seeing a shark coming up under their board when they see the neons coming up under their net! The neons don't get in the plants much, so I think the babies will feel safer now.

I also shifted the net to the edge of the tank where the current isn't as strong so the egg yolk mixture would not get sucked out so fast. Also put canopy plants around the sides. I left a bit of egg yolk in bigger particle to leave while I am at work. Not sure they can eat it, or maybe it will pull apart with the current throughout the day.

Fry are bigger, but not real active. Is this normal? They move around most when I move the net.

I've heard that you can put this egg yolk mixture in a spray bottle and spray it into the tank.

I've never tried using a spray bottle, but be warned, dont use alot of the egg yolk!! It will cloud your water super bad, it takes like 3 waterchanges to get it out. and I hate "grey" water for 3 weeks...

Bow down to MTS!!!!!!!!

I've also read that just a tiny amount will go a long way.
