The jeweled moray gets its name from the bright yellow spots scattered across its dark brown body that resemble jewels under aquarium lighting. Native to the Eastern Pacific from the Gulf of California south to Costa Rica, less commonly available than Indo-Pacific morays but a striking display species when found. Mid-size and reasonably manageable for keepers with 125-gallon FOWLR setups.
Native range: Eastern Pacific (Gulf of California, Mexico, Costa Rica). The jeweled moray is a member of the Moray (Muraenidae) family. Most specimens in the US trade are wild-caught from collection points in their native range and shipped through Indo-Pacific or Atlantic marine wholesalers. Wild-caught morays often arrive with internal parasites and shipping stress - a 4-week quarantine in a separate system with prazi and metronidazole prophylaxis is the standard reef-keeper protocol before display introduction.
Tank size: 125 gallons is the practical minimum for a single adult. Substrate should be marine sand 2-4 inches deep - fine grain to prevent abrasion. Hardscape should provide multiple cave structures, PVC pipe segments, and overhangs that allow the eel to choose its preferred resting position. Lighting can be standard reef LED; morays do not require special light spectrum. Filtration should be oversized - morays are messy eaters and produce significant nitrogenous waste. A skimmer rated for at least 1.5x the actual tank volume is the standard for moray-housing FOWLR systems.
The lid is non-negotiable. Morays are exceptionally strong jumpers and escape artists. A 1cm gap is enough for an adult specimen to find and exploit. Hood-style covers work; rimless tanks need custom acrylic or glass cut to seal completely.
Primary diet: Frozen silversides, krill, squid, chopped fish. Morays are obligate carnivores. Feed 2-3 times per week for adults, daily for juveniles. Use feeding tongs rather than dropping food - morays learn to associate tong tips with food and develop reliable feeding responses within 1-2 weeks. Variety matters: rotate between silversides, krill, squid, chopped scallop, and occasional whole shrimp for nutritional completeness. Avoid feeder goldfish - they carry thiaminase that destroys vitamin B1 and leads to long-term neurological problems.
Safe: Large peaceful predators: large angels, peaceful triggers, large tangs..
Avoid: Fish under 3", small inverts, conspecific morays..
Not bred in captivity.
Limited availability; aggression toward small tank mates; jumping.

The Jeweled Moray is rated intermediate to advanced difficulty on this care sheet. It needs a tank of at least 125 gallons, a temperature of 72-80°F (22-27°C) and salinity of 1.024-1.026 SG. Adults reach about 24-30 inches (60-75 cm) and live 15-20 years.
