I've had my Betta fish, Roger, for about 2 years. He's in a 10 gallon tank with live bamboo and plenty of hiding places, but he really only hangs out in the big bamboo leaves in the upper right corner. I know Bettas are solitary fish, but they can have tank mates. He lives with two little african dwarf frogs and 5 little neon tetras. The filter we're running produces a bit of a current, which I think is bad for him (he really only hangs out on one side of the tank) and I'm trying to change out. Am I giving him a good life? He's bright blue, but his tails are showing a little bit of fringing which I'm worried about....
