Just introduced a flame hawk to my tank, he has adjusted very well. He doesn't seem to bother any tank mates, but my 2 skunk cleaner shrimp are terrified of him. He seems to control the section of the tank they are accustomed to. The shrimp have relocated by the return pumps, and try to stay away from the hawk fish. Both shrimp are larger than the hawk fish, and he doesn't pay attention to them. Am I just paranoid, or do I have a potential problem?
