Why...?
Btw, headcouger, just because it "looks" fine, doesn't mean it is. Someone can say that a betta in a glass cup is healthy, they might even say thriving, but what is he really? Surviving. Barely. And he won't get near 5 years. More likely 5 weeks in that.
Your cons are not brackish fish. Stop killing fish and snails, please. It would be appreciated. Bye-bye harlies to a new tank, with oh, say, 5 others? And those columbians will get 18" and eat as much as you do, and almost any fish short of a tankbuster they're kept with. The goldfish can't stay in that tank. Remove it, you're fish deffinately don't appreciate on OS tank and poorly stocked tank.
