Fighting fish

Question
My African Dwarf Frog keeps on biting my new black molly, what can i do? i don't want to return the fish.

Answer
Miley,
The best thing unfortunately is to either remove the frog or the molly. The 2 should not be in the same tank since mollies need salt in their water and the frogs don't. You also don't want the tank filled with a frog because they have to come to the surface for air and they are not good swimmers.
