Eels Species


Eels are members of the Muraenidae family, which contains approximately 15 genera and 0ver 200 species. Eels are a commonly kept group of fishes due to their unique looks, interesting behavior and general ease of care.

The Snowflake Moray Eel (Echidna nebulosa) is one of the most commonly sold eel species. Other eel species commonly seen in the aquarium trade include the Chainlink Moray (Echidna catenate), Jeweled Moray (Muraena lentiginosa) and Whitemouth Moray (Gymnothorax Meleagris).


Moray eels are found in all the world’s oceans.  They can range in length from 4“ (11 cm) to 13’ (4 m), though most species available in the aquarium trade are much more moderate in length. Moray eels are cave dwellers, who rely heavily on their sense of smell for hunting down prey. They are known to consume octopus, squid, large crustaceans and fish.

Captive Care

Eels make great aquarium inhabitants, provided their husbandry needs such as diet, water quality and tank space are met. It is important to remember that moray eels are predatory in nature, and they may consume other aquarium inhabitants. Eels are also known as escape artists, so a tight-fitting lid it paramount to maintaining these fish in captivity.

Most eels prefer a temperature range of 72F (22C) to 80F (26C). Eels can be considered a reef safe fish, as they will not harm or consume corals, however they are likely to consume some ornamental invertebrates as well as fish.

It is important to consider carefully what species of eel may be best for your aquarium. While smaller species such as the Golden Dwarf Moray (Gymnothorax melatremus) are suited to tanks as small as 20 gallons, larger species such as the Green Moray (Gymnothorax funebris) may be better suited to a larger tank.

What people are saying about PE:

After feeding my seahorses your mysis for about 3 months; they are fat and happy!!! they give me baby seahorses (at least 300 ) each 14 days... So I'm very satisfied of your mysis.The frozen mysis is about 70 per cent of their diet.

I am keeping these Indian mudskippers -- very cute -- about 3-4 inches long. I've been feeding them frozen bloodworm, and decided to try them on mysis. I feed them in a "shallows" in the 150 I have set up for them. The minute the mysis hit the water they were on it, frozen and all. They gorged until their little bellies were almost bursting. I have yet to see an aquatic creature that does not go absolutely nuts over PE Mysis.

I picked up my Mysis today and they arrived wonderfully. All the fish I fed them to, absolutely devoured them. They are my Frontosas new favorite food. All my Discus ate them up eagerly...heads and all!! I want to thank you again for your excellent service and product.

I have a large saltwater aquarium (220 gallons) with very expensive fishes and invertebrates. I tried to feed them with your PE Mysis and they really went crazy about it. Since that time, some of my fishes refuse any other product I offer them!
