Is it safe to mix different species of frogs or toads in the same tank or pond?
WHEN IN DOUBT, NO! I can’t stress this enough! Definitely some species do ok together, but in many cases this can have deadly consequences! One visitor wrote me with an anecdote about having a Firebellied Toad and a Pac Man Frog in the same tank. Even though the Firebelly was half the size of the Pac Man, after 15 minutes, she returned to the tank and in horror found the Pac Man Frog dead! The Firebellied toads have toxins in their skin (hence the neon warning on their bellies) which, while not harmful to humans, is quite deadly to some other species! Similarly, Pickerel frogs, which look very much like Northern Leopard frogs except that their spots are more squarish, have very toxic secretions (hence should NOT be mixed with the similar looking Northern Leopard frogs.) Cuban Tree Frogs have been known to EAT other types of frogs! NEVER NEVER mix a Cuban Tree Frog and a Green Tree Frog! Some Cuban Tree frogs will even eat members OF THEIR OWN SPECIES if they are big enough! (eeeew!) An
