Understanding Reef Compatibility

Reef safety is not always black and white. While the species above are generally considered safe, individual fish can sometimes behave unpredictably. Factors like tank size, feeding schedule, and tankmate selection all influence behavior.

Species rated “Caution” may be suitable for reef tanks under specific conditions, while “Not Safe” species are known to damage corals or eat invertebrates. Always research individual species thoroughly before adding them to a reef system.
