So...right now I have two bettas I am trying to take care of. Each in their own 2.5 gallon home. Some one suggested I get a 10 g and divide it. Been thinking maintenance would be easier than two small tanks. But then I got reading about tank mates for my bettas and bioload. I would love to get an apple snail for each side and neon fish as so pretty but should be in schools of at least six I heard. What are my options?
