My albino cory eggs hatched 6 days ago. Changing water daily, 2 1/2 gallon bare bottom tank, 77 degrees, airstone, slowly dying, any suggestions? Thank you, Lary Smith

It's only forever; not long at all...
What are you feeding? Are you dechloring (obvious I know but thats all I can think of). Any sprays or similar being used in the room that could get into the water?

Clean room with 64 tanks of guppies. I sprinkled a little powered baby fish food and added about a drop or two of live baby brines. Use Prime to dechlorinate. Try to keep bottom as clean as possible without disturbing them. Thanks for the reply.

No idea then. Wait for inch or someone clever to come along.
Hi reticulata 
Corys will naturally have some loss in numbers during the first few days, but this should not continue in great numbers.
Since they have just hatched, and spent a day or two absorbing their egg sacs, they have only been eating for 4 days, so perhaps the food is the problem. They are very tiny compared to guppy fry and the dry food might be to large for them, at least at the beginning. Why not try Liquifry or something similar for a few days. Then, they should be able to take bbs, microworms or flake.
How much of the water are you changing every day? I have never used Prime, but if it has anything like aloe in it, I would suggest switching to something more basic.

Hi Dwarf_Dude
In almost all cases your question would have been an excellent one. But raising corys in a bare bottom tank with an airstone for the first few days means that he is working with an uncycled tank.
I do it this way too, and depend on daily water changes to remove the uneaten food and fish wastes. This keeps the water clean and fresh, so cycling isn't needed.
In another week or so, I would change the airstone to a sponge filter and let the beneficial bacteria start to grow on it. That way, by the time it needs to be cycled, it will be.

Thank you Inchworm:
I thought about Liquifry but gave them some powdered live bearer food (almost like flour). Anyway it sounds as though I'm on the right track, I'll try the food change. (See my other direct e-mail to you for the history). Couldn't see a complete ingredient list on my Prime so sent Seachem an e-mail. Thank you.

Hi reticulata
After reading your email, I have a couple of suggestions to make.
First, corys are very sensitive to their water conditions and dirty water will cause bacterial growth and die off. Your tank is small, and with it only partially full, spoiled food can cause serious problems very quickly.
I use a bare bottomed tank for fry too, but suggest a 10 gallon as a spawning tank, and later a fry raising tank. I keep it full of water too. This way, daily water changes can keep it fresh and disease free. The tiny fry won't produce enough waste to effect ammonia or nitrite levels, but uneaten food can do a lot of harm.
Actually, I don't know why the cory fry couldn't eat powdered food from the start, but I wouldn't take a chance. I use the Liquifry, (just for the first few days) which can be flushed out through water changes, then microworms. The good thing about them is that they live for a few days, so they are safer, in this respect, than dry food. I have never used bbs, but have heard of members who use them with success.
In just a few weeks, you can feed regular flake and watch as they gather around the large pieces and eat them completely.

It's interesting that after sweating my newly hatched albino cory babies in their own tank that I found a baby about 3/4" long in my spawning tank with eight adults that somehow hatched and made it. Nature has it's way.

A little update on my albino cory breeding "program." I've had two large and several smaller spawns in the past month. The first large spawn of about 100, approximately 50 are doing very well after three weeks. Three smaller spawns have hatched and as an experiment after they were about 5-6 days old, I placed them in a 2.2 with the two that survived from my very first spawn over a month ago and they are all doing great. My thought is the younger ones are learning from their older siblings. Sponge filters, airstones and 50% water changes from the 10 gallon spawning tank daily. Two days ago about 150 hatched so we'll see if I'm as good as I think I have become (haha-trip on my own ego). So far no success on my adolfois.
Hi reticulata
It sounds as if you are doing very well with your fry. Corys do have a fairly high rate of die off in the first days, but once you get past that, and they get a little size on them, they do well.
Keep up the good work and soon you will have more corys than you know what to do with!
