Keyhole Limpit
Scientific Name: Megathura crenulataReef Compatibility: See Notes
Minimum Tank Size: 10 gal
Max Size: 1”
Food/Feeding: Herbivore
Notes: The Keyhole Limpets are typically half an inch long, or smaller, and feed on unwanted filamentous algae, cyanobacteria, diatoms and even hydroids. Limpets have an oval, laterally compressed shell that tapers to an off-centered blunt point. Limpets have a tiny hole at the crest of their shell where it becomes a point, which they use for waste and water exchange.
The Keyhole Limpit should not be considered for tanks with SPS corals, as they will consume them if there is not enough other food available.
