I bought a small golden gourami to add to my big tank about 2 weeks ago. My large blue gourami would not let her be. He picked at her and chased her. (Genders are guesses here, but I suspect since they are not getting along, they might both be male). Anyway, I decided that I had to remove her from the tank before he killed her. So I bought a 12 gallon Eclipse tank with the intention of putting her and 1 or 2 other small tank mates in it. So the 12 gal. is set up and the golden gourami in swimming around in there happy as can be. Being the softy that I am, I think she needs tank mates to keep her company. I get some advice from the fish manager at the store and take home 3 cherry barbs. I put them in the tank and the golden gourami won't leave them alone. She chased them constantly. I finally moved the 3 cherry barbs to the big tank where they seem to be adjusting nicely. None of the other fish in that tank are bothering them. Do you think the gourami needs a tank mate? Does a single fish do okay in a small tank? Can a fish become possessed? (just joking..lol) Should I take the golden gourami back and trade her in for somefish that is more friendly/docile/less homicidal??
