We have a 10 gallon tank with 4 female betta fish. They're all happy and get along well, I haven't seen them get territorial since the day we brought them home almost a month ago.
Well, my roommate wants to get a new fish for our girls. I told her I wanted a tetra, but apparently tetras like other tetras around too, and our tank is too small for 2-3 tetras. She was thinking about getting a Ryukin goldfish. But, I think that might be too big for our 10 gal. And we don't have room in our apartment to get a bigger tank.
What other small fish could we get? Minus platies, I don't like them too much, they look too much like guppies.
I also have a 5 gal tank, and a 1 gal bowl. I really want to get a male king crown tail or female half moon for the 5 gal just to be alone. What do you think?
