my dad is about to purchase a 18x 18x 24inches reptile tank fully equiped. he wants to have a a group of animals in there. the guy at petsmart said he could put 10 aniles in there no problem but sounds retarded. my dad is more curious about putting like 2 green anoles a bahaman anole a long tail grass lizard and a gree tree frog together. what do you guys think?
