I'm thinking about getting more into the rhacodactylus species, like gargoyles, cresteds and leachianus. Currently I have one crested gecko, but she is still pretty small. I will buy a bunch of exo terra tanks, but I'm still not sure of which sizes that would be good for cresteds, gargoyles and leachies. Of course it depends on the size of the animal (and perhaps location, leachianus), but I'm thinking of starting with adult or well-grown animals. Do you think 18x18x24 is good size for cresteds and gargoyles, and 24x24x36 for leachies? Thanks !
