Not a lot, darker clowns are pretty aggressive once they pair and with an anemone you risk the clowns getting big enough to spook the fish directly into the anemone.
What about a pair of yellow watchmen gobies? They’ll dig a hole and make a house for safety, if the clowns swing by they’ll dart into their house. I think they are really pretty too.
Ya, some bottom dwelling goby would be great. You could do a pistol shrimp and goby combo or just gobies. Possum wrasse would likely do pretty good. Or maybe a cardinal
