I have clowns, zebras, and skunks all together and have no problems at all. A lot of people say that skunks are aggressive but from what I have seen, they are more curious than aggressive. They swim along side a fish and it looks like they are chasing them, but after a lot of observation, I think they are just trying to check them out. Dojos are a cold water but can be kept at the lower 70s, which the others can also be kept at. As long as you provide plenty of hiding places, you'll be fine with almost any combination.
