Raising fry question

[TJR]

Need advice! I have a great pair that are completely healthy, and they have sucessfuly raised their fry. Once the fry get to be around 3-4 weeks they start dying off. Their does not seem to be any breathing dificulty or external signs of disease. The only thing that I can think of is a bacterial infection or something that is not visible. I have Prazi and Formulin. Should I start a treatment after I seperate the fry from the parents? What do you reccomend?
Any help or hints will be appreciated.
Thanks,
Treva

Raising fry is a lot of work and attention to detail. Wipe your tank every other day, clean your sponge every other day minimum, waterchange 100% per day or more, feed,feed,feed and clean some more. After they are 1.5" they are much tougher, two weeks later they are 2" and ready to sell ;) .

That is a very common occurance. I treat my fry for flukes at about 10 days free swimming as a standard practice, using 2 drops to the gallon of formalin. There are other good flukes treatments out there as well. They don't die off any more.

I just do daily water change (with 24 hours aged & heater water)... feed a lot .. .but never did use any medication. I feed them chopped frozen blood worm, color bits, golden pearl and flake powder.

You might want to elimenate the the bloodworms from their diet at this age. Very small discus have difficulty digesting bloodworms and a combination of bloodworms and some prepared dried foods have been known to cause intestinal problems in young fry.
