Purple & Orange Reef Lobster

🦞 Overview of the Purple & Orange Debelius Lobster (Enoplometopus debelius): Takeaway: The Purple/Orange Debelius Lobster is a vividly colored, nocturnal Indo‑Pacific reef lobster known for its purple body, orange legs, and semi‑aggressive, territorial behavior. It’s reef‑safe with caution and thrives in tanks with ample caves, rubble, and stable water chemistry. 🌈 Identity & Appearance Scientific name: Enoplometopus debelius Common names: Debelius’ Reef Lobster, Purple Reef Lobster, Purple/Orange Reef Lobster Coloration: Lavender‑purple body with orange or red legs, violet or dark spots, and elongated claws tipped in orange/white. Adult size: ~10 cm / 4" (some sources list up to ~5") Body form: Crayfish‑like, compact, with long antennae and flat defensive claws. 🌍 Natural Habitat & Behavior Range: Indo‑Pacific—Indonesia, Philippines, Solomon Islands, Papua New Guinea, and Indian Ocean regions. Habitat: Rocky crevices, rubble zones, reef flats; hides deeply during the day. Activity: Strictly nocturnal in the wild; may become more visible in aquariums over time. Temperament: Semi‑aggressive, territorial toward other lobsters and small inverts. 🧪 Tank Requirements Minimum tank size: 26–55 gallons depending on source; 30 gallons is widely accepted. Salinity: 1.023–1.025 SG Temperature: 72–81°F (22–27°C) depending on regional guidance. pH: 8.1–8.5 Aquascape: Deep substrate for burrowing Heavy rockwork with caves and crevices Dim or shaded areas for daytime hiding Copper‑free environment (high sensitivity) 🍤 Diet & Feeding Diet type: Omnivore Wild diet: Detritus, small invertebrates, organic matter. Captive diet: Sinking pellets Frozen mysis, chopped seafood Occasional algae wafers Feeding behavior: Primarily scavenger; becomes more active at night. 🧑‍🤝‍🧑 Compatibility & Reef Safety Reef‑safe: Yes, with caution—may prey on very small fish or shrimp. Tankmates: Peaceful fish of similar size Avoid tiny gobies, nano shrimp, or slow‑moving inverts Lobster pairing: Keep one per tank unless you have a confirmed mated pair; highly territorial. 🐾 Molting & Care Notes Requires secure hiding spots during molts; exoskeleton hardening takes hours to days. Sensitive to unstable parameters—best in mature, stable systems. Lifespan: 5–10 years (typical for species in this group). 🧬 Taxonomy Kingdom: Animalia Phylum: Arthropoda Class: Malacostraca Order: Decapoda Family: Enoplometopidae Genus: Enoplometopus Species: E. debelius
