Field Frame Friday: Garibaldi neighbors respect the “no trespassing” signs.

Garibaldi (Hypsypops rubicundus) are territorial fish. Males will clear bottom territories and combat other fish and even SCUBA divers that come too close to their territory. However, it is uncommon that there is intraspecfic aggression; Garibaldis generally “respect” each other’s territories, so there is no need for aggression within species.
