I have used these tanks for years for my snakes; both corn & king snakes. Recently purchased a new one to replace an old one that had issues with it from repeated moving: Margate to Faversham, Faversham to Bognor Regis, Bognor to Carlisle - the plastic attachments holding part of the structure had had it, & there were various knocks & bangs damage to the sides, so I replaced the oldest one I have had for 6 years. Would be good for lizards too: I know a guy who has 2 bearded dragons, housed seperately, in this same kind of tank.
