Last week I bought a flame red dwarf gourami, hes been getting on great and has settled well in my tank. But today I bought two more, both males. As soon as I introduced them to the tank my first gourami "Buster" as I like to call him went nuts. Hes been chasing both of them around for hours now, taking nips at them. The two new fish get along fine and even swim alongside each other, but Buster isnt liking them one bit. I want to know if this is a just a temporary thing or not. Will he settle with them after a day or two? Or is this going to be a fight to the death? Is there any way for me to stop him bullying them?
