I have a ten gallon tank with about fifteen fancy guppies and about five more fry, three new glowlight tetras, a cory catfish (bottom feeder), and an algea eater. I really want a betta fish. If I bought a tank for a betta than I would have to spend quite a bit of money and I don't really want to do that. I know that it would probably be bad if I put a betta in my tank but it does work for some people. What do you think? And please say why, thanks.
