I've learned quite a bit in the short amount of time I've been here but while I've been focusing on learning about my new fish and the aquarium I got I haven't learned enough about my 2 Bettas. I received two Bettas a couple years ago from a neighbor housed in two seperate bowls put together looks like one. She told me change the water every couple weeks with distilled water and they would be fine. So far they have been fine but it seems like I'm going about it wrong. They need to be in an actual aquarium? Do I have to get two seperate aquariums or can I try putting them together in one? Do I put them in my 70g or are the tank mates not good for them? I'm away from home for a few days so I'll have to wait to see if they're both males or not. Why is it most stores sell bowls for Bettas if everyone seems to agree they shouldnt be in a bowl? Some input on what I should do with them would be greatly appreciated.
