Veterinary & Aquatic Services Department, Drs. Foster & Smith

Tank mate compatibility is crucial to a successful and healthy marine aquarium. Incompatible species will increase stress in the fish that could result in disease and considerable loss. The chart below may be helpful in selecting fish that will live compatibly with their tankmates.

These are only guidelines. Remember, no guarantees can be made, as there are individual variations between fish, commonly a result of age, size, and whether the fish is wild harvested or tank raised. Also, particular species within a group of fish may vary in temperament and may not correspond with the guidelines below. Click here for a larger version of the chart.
