I am new to Betta owning. I purchased some adults from someone and they gave me 18 fry that are 2 months old. I have been feeding them Brine Shrimp Flakes crushed from Kens in the morning and Live Baby Brine shrimp in the evening. Is there something else I shold be feeding them. I have one that sometimes lays on its side at the top of the water and one that seems to have trouble swimming down and staying down . The rest seems to be doing fine. I do fast them one day a week . Any advice would be greatly appreciated.
I am not new to raising fish as I have 21 tanks with angelfish in them and I do breed angels and hopefully going to try and breed some Bettas in the future.
