Hey guys, So I've had my tank for a while now (had it since March), and I currently have 5 neon tetras with 2 young mollies. I used to have 3, but one of them died since she was pregnant and got very stressed out (I also used to have 1 otocinclus; I didn't know they had to be grouped together so he was very lonely for a while and would never come out of his cave unless I would clean the tank, and he eventually died). I got the mollies from my science teacher and they're absolutely wonderful; they get along great with my neons. When I first got them they were really tiny since they were just born months prior, but now they're bigger and almost fully grown. Anyways, I really want a betta. I have heard that females can be kept with neons, but I'm not sure about the mollies. The mollies don't show any sign of aggression, except the older one (I named him Gandalf ) will sometimes chase the younger one around. Would a female betta be ok with these guys? I really want one, but I love my current fish too much to give them up just to get a betta. I think my tank is around a ten gallon; I'm not sure.
