I just saw somewhere that fire belly toads can be kept with arboreal lizards with high humid but then what if my gecko or it attacks it both powerful bites for their size and one with poison sacks
You are keeping a Crestie with FBT's and "what if" plan to add arboreal lizards ? This thread is starting to look like a train wreck waiting to happen .
Remember to take care of the enclosure and it will take care of your frog !
