Goldfish and African clawed fish

I've found that keeping African Clawed Frogs tends to be a species only tank (due to their size, and fast movement to catch any smaller fish that move around/above them) unless you have a large long tank. In terms of keeping them with goldfish, I've seen it done, although they come from totally two different habitats in the wild, so their care requirements are different and may result in one species suffering a tad more than the other.
