my LFS has female honey gouramis. if i move my fish into my 20 gallon, could i fit my one male honey gourami and two females? plus the 6 glowlight tetras? would they have enough room if i provided plenty of hiding places and plants? i'm going to go with a 40 filter, so filtration isn't a problem, just territory. on more than one occasion, my male honey gourami has chased the tetras away from his "spot" but he's never inflicted damage. i just wonder if he would be too agressive towards the females or if they could hold their own?
