Hi,
ADFs are generally sold as congo frogs but check the ID in the pinned topic at the top. I personally keep mine seperate from my fish as they would starve. They are a bit stupid when it comes to food and it needs to be put directly in front of them or they will miss it, they wouldn't stand a chance with my fish. They would probably be ok in a community if you have an external filter that won't break their legs, small fish that won't eat them and if you are willing to feed them with a turkey baster. If you search the forum you'll find loads of info.
Hope this helps
Emma
