Reaching an adult size of approximately 2 inches, this crab is well known for its utility in reef aquariums as both an algae grazer and opportunistic scavenger. While generally peaceful toward fish, it may become opportunistic with very small invertebrates if underfed. Its bold coloration and algae-cleaning behavior make it a functional and attractive cleanup crew addition.\u003c\/p\u003e\n\u003cp data-start=\"624\" data-end=\"1028\"\u003eThe Ruby Red Emerald Crab thrives in established reef aquariums with abundant live rock and natural algae growth for grazing. A minimum tank size of 10–20 gallons is recommended for a single specimen, with larger systems preferred when multiple crabs are kept. This species should be added early in the stocking process once the tank begins to develop algae and biofilm for natural feeding opportunities.\u003c\/p\u003e\n\u003cp data-start=\"1030\" data-end=\"1391\"\u003eAs an omnivore with a strong herbivorous tendency, the Ruby Red Emerald Crab benefits from a varied diet of algae-based and supplemental marine foods. Offer Julian Sprung’s Sea Veggies in an algae clip, New Life Spectrum Algae Pellets, and small frozen meaty foods such as PE Mysis or Hikari Brine Shrimp to maintain health, coloration, and consistent activity.\u003c\/p\u003e\n\u003cp data-start=\"1393\" data-end=\"1431\"\u003e\u003cstrong data-start=\"1393\" data-end=\"1422\"\u003eApproximate product size:\u003c\/strong\u003e 0.5-1.5\"\u003c\/p\u003e\n\u003cp data-start=\"1433\" data-end=\"1760\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eWe maintain a rigorous, veterinarian-approved quarantine program that includes proactive treatments, careful observation, and daily monitoring to ensure the highest standards of fish health.
