I've had Leo for a little less than a week. I've noticed no signs of illness, other than the fact that he is not eating.
He lives in a 10 gallon tank, divided with another male, Harvey. I didn't divide the tank between them until a couple of days ago. This problem began before Harvey arrived in the tank, though. I also keep a submersible heater on at 80 degrees constantly. Leo has not been eating at all. I've tried freeze-dried bloodworms as well as BettaMin Tropical Medley flakes. He swims past them, and sometimes even stops to look at them. Harvey, on the other hand, has a huge appetite. Leo also seems to sit at the bottom more often than Harvey. But he is still energetic. I'm not sure if I should really be all that worried, but I'd like it if I could hear from someone about this. I love Leo, and I would surely hate it if something were to happen to him. :( Please help.
