Ok we have about 10 geckos, ranging in sizes. Up till now we have kept them in terrariums that are 24 inches tall by 18 wide and deep. We keep three females per male, but recently have had problems with aggression between geckos. Now we have either tailess geckos, or tails that have been bit and turning black. We have been seperating until we found the one causing the problem. But i do not have enough cages to keep every gecko seperate, nor the space for such large cages. Not to mention cost of the cages is not cheap. As our eggs hatch we need more space. Can anyone tell me how your geckos are housed? Does anyone use racks, and if so what kind of racks. I breed balls and have multiple racks, but the tubs all seem to small for the geckos. Please help
