Hi! I have a 20 gallon tank with three mollies, three platys, a BN pleco, and nerite snails. Yesterday I noticed fry in the tank. I’m not sure how old they are, but there were only a few left by the time I saw them. I was going to leave them in the tank but I felt bad and ended up moving the two that I saw to a 2 1/2 gallon tank. I put Java moss in the tank and i didn’t add substrate. I fed them crushed flakes. I’m planning on buying a sponge filter and a small heater later today for them. I also have frozen brine shrimp that I can feed them. Is there anything else that I should be doing? I don’t know if they are mollies or platys.
