Ok here I'll disect your post. Animal by animal.
Hi. I have a Pac-man frog, and I know he has to be in a cage alone. What I need to know is, of all these other pets that I have, which are compatable to live together? I have several Green Tree Frogs, an Oriental Fire-bellied Toad, a Southern Leopard Frog, an Emerald Swift, several Anoles, and some land Hermit Crabs. Does anyone KNOW, I mean really KNOW, which animals are safe to live with the others? Thank you. Mar
Pac-man Frog- will attempt to eat anything in the same tank.
Green Treefrog- aboreal
Oriental Firebellied Toads- poisonous(will kill everything in the same tank)
Southern Leopard Frog- needs a set up of 50/50 land water and plenty of space
Emerald Swift- needs a basking area of about 80-90 degrees(will fry frogs)
Anoles- aggressive, will attack everything in the tank with it
Hermit Crabs- will attack anything in the tank with it
All that aside from all the stress they cause each other and diseases they transmit to each other, and parasites they transmit to each other.
