I should have my 20 gallon going next week, and to raise the babies I have the 6.6 gallon bookshelf tank which is where the 3 adults are now, a 3 gallon Eclipse system and I also have a 6 gallon Eclipse which is what I used for my White Cloud fry.
Let's see if I'm lucky enough to get them to hatch first. The 20 is going to be for the adults. If I need to I can buy a 10 gallon to raise some babies. I have one of those sponge filters that you attach to an air pump.You could raise about 8 to adulthood in a 20 gallon.
