So my bf's sister has 2 bettas a male and female. She just asked me if I would take them and keep them at my house. I'm not sure what I should do. I already have 13 of my own to take care of and keep up with. However her fish are in less than 1/2 gal bowls, the male is in one of the triangle small "bowls" they have at the fish stores and the female is in a bud vase. I have shared with her that they need more space than that, but her parents don't care that much about a "stupid" fish. I know that I have 2 open 1gal tanks right now here, and that they'd probably do much better here with me... I don't know

Should I take them in?
