Sally lightfoot crab

Sally Lightfoot Crab

Scientific Name: Percnon gibbesi

Small Fish Safe: With caution – may become opportunistic as it grows

Invert Safe: With caution – may harass smaller inverts

Coral Safe: Yes

Adult Size: Up to 8 cm (leg span can exceed 15 cm)

Diet: Omnivore – eats algae, detritus, and meaty foods

Why We Like It:

Fast, agile, and striking, the Sally Lightfoot Crab is a rock-scaling scavenger that adds serious energy to reef and FOWLR setups. Great at algae control when young, but as it matures, it may become bold enough to pick at weaker tankmates. Best kept in larger systems with stable rockwork.
