They'll do better if you feed them a variety of foods, mine get shrimp pellets, white worms, frozen blood worms and the occasional algea wafer that I put in for th GBAs
And if it is bare bottomed tank you can take the eggs out quite easiely and pop then in an eggubator
I have my pandas in a normal tank with silica sand and largish rocks for the babies to hide in till they get bigger.
I would be interested in some fry if you are successfull, have had a lonely girl for 2 years now, haven't seen any down here for a while
