Pitho Crab

Overview

The Pitho Crab, also known as Pitho Mirabilis or Roughed Emerald Crab, is a peaceful and efficient algae eater prized by reef aquarium enthusiasts. It plays a vital role in maintaining a clean and healthy reef environment by controlling nuisance hair, bubble, and turf algae without damaging delicate corals. Ideal for both beginner and experienced hobbyists, this crab is a quiet but powerful member of the cleanup crew.

Colorization

The Pitho Crab sports a mottled tan and brownish-grey shell with a rough, hairy texture. This natural camouflage allows it to blend seamlessly into live rock and reef substrates, making it less visible to predators and helping maintain a natural reef aesthetic.

Size

This species typically measures between 1 to 1.5 inches, a compact size that fits perfectly within diverse reef tank setups and crevices without overcrowding or stressing other inhabitants.

Feeding

Primarily herbivorous, the Pitho Crab actively consumes nuisance algae such as hair algae, bubble algae, and turf algae. Supplemental feeding with algae wafers or marine herbivore foods can support its diet, especially in tanks with limited natural algae growth.

Aggressiveness

The Pitho Crab exhibits a peaceful temperament, posing minimal risk to corals or tank mates. Its non-aggressive behavior makes it a favored choice for reef aquariums seeking natural algae control with low conflict.

Care Level

Easy to care for, the Pitho Crab requires stable reef tank conditions including proper salinity, temperature, and water quality. Regular monitoring and slow acclimation during introduction are recommended to ensure long-term health.
