corns are more forgiving I have 2 that re being kept a room temp because I need to build a second rack unit (which i got to gather the funds for the wood). these guys are kept in a 75-82 degree room,and are doing great. just make sure that you can lock ( secure that cage lid ) they get loose easy. i happen to check on mine last night and found one of the corns trying to getinto the asf cage . the little guy stayed inside the tub for since I aquired it until last night.. I am gonig to soften and warp the lid so when it lockeddown it tigt alway around..
