Mine will definitely stay in the 10g tank until they're roughly the size of the pygmy corys. Then OH and I have a wee disagreement over the best thing to do. They won't be able to move in with their parents until they are big enough to be raphael-proof, so he wants to move them to the L199 tank when they're roughly the size of the pygmy corys and grow them out there. I'd be more incline to add some sand to the current 10g and keep them there. Not sure what makes the most sense or is best for the fish.
On that note, is there a point where I should be adding sand to their little tank?
