Scarlet Reef Hermit Crab

Care Summary

The Scarlet Reef Hermit Crab is a reef staple, a small and peaceful algae grazer with bright red legs that stands out against rockwork and sand. It thrives in reef systems of virtually any size and is one of the safest hermit choices for mixed invertebrate tanks, but still keep spare shells available to minimize conflicts. Its main drawback is a limited impact on anything other than soft filamentous algae, so do not rely on it alone for hair algae outbreaks. No target feeding is needed as it continuously scavenges detritus and microalgae, making it a low-maintenance workhorse for any cleanup crew.
