Some Backstory First: I've worked with animals before, but have never owned a fish. Very recently, my roommate moved out and accidentally left her Bettas here. She was unable to come back for them when originally intended. I've just gotten back into town yesterday, to find they still hadn't been picked up. It's been almost two weeks. While I was gone one of the poor things has died, and one of the remaining two isn't looking so great. I ran to get them food, and one is eating fine. The other one looks like it's struggling to get to the top of the water, and there's what I think are scale flakes all along the bottom of his bowl. Movement: Is this something I can help him recover through? Would it be more humane to just put him down? I'm determined not to let another one of the die if I can help it, they're my babies now. I need all the help I can get. What kind of kit do I need to help them live the best they can? I'm a student, so I'm on a tight budget, but I'll do what I can.
