I have two african dwarf frogs in my molly/platy tank and they are doing great. These frogs are very peaceful and are funny to watch. One thing about them is that if they are kept with any fish that will breed, the frogs will eat a lot of the fry, they dont do much until you see a baby fish swim in front of them, and then they fly like the wind catching them. So, if you want to have babies, i wouldnt suggest any frequent breeders. If you dont really want the babies and like guppies, molly, or platy, or frequent breeders then the frogs will take care of that problem. Also the baby fry are a good source of nutrician for the frogs. I have snails with them and I also had a chinese algea eater. So anything that is a very peaceful community fish will do great.(to agree with the last person, i cant see the name while im posting) I love having them around. But do watch like the last person said about the claw frogs. If for some reason, those are the ones you have, take them back. Unless or course you want to keep them. They will eat anything, and are messy messy messy. Good luck!
