Who Gives A Fish Forums

Thanks for the tips! I'll switch to microworms and add some java moss. Water changes are currently twice a week, so I'll reduce that. Appreciate the help.

I've got a batch of Corydora fry in my 20-gallon tank, but they're not making it past the first week. Water params are good, 0 ammonia, 0 nitrite, 10 nitrate. Temp is 76F, sand substrate, and a sponge filter. Feeding them crushed flakes and baby brine shrimp twice a day. What am I missing?
