   We bought this eel as a "Leopard Eel" but have failed to find out exactly what kind of eel it really is. This eel has the coloring and looks of the Yellowhead Moray Eel, Dark-spotted Eel, or Fimbriated Moray Eel, Gymnothorax fimbriatus. It has connected spots in a less random manner than those we've seen in Atlases, however, the moray's are known to come in a variety of patterns!

   The Yellowhead Moray Eel, Dark-spotted Eel, or Fimbriated Moray Eel is like most other, being a hardy animal that likes holes to hide in and eats live, meaty foods. This species is commonly seen and will only grow only up to 30". It is a hardy and fairly peaceful species for the marine aquarium.

   The Leopard Moray Eel, Gymnothorax undulatus, is not a good choice for a marine aquarium as they grow upwards of 6 feet!

   If you find one that is called a Leopard Moray Eel, and it has the coloration and patterning of the one above, you most likely are looking at the Yellowhead Moray Eel, Dark-spotted Eel, or Fimbriated Moray Eel rather than a "Leopard Moray Eel".

Yellow Edged Moray Eel - Gymnothorax flavimarginatus

The yellow edged moray eel (Gymnothorax flavimarginatus) is a member of the family Muraenidae. The yellow-edged morays commonly inhabit drop-offs in coral or rocky areas of reef flats and protected shorelines to seaward reefs. The depth of the eel in the video is evident from the need for a light. They feed on cephalopods, fishes, and crustaceans. Their distribution includes the Indo-Pacific from the Red Sea and South Africa eastward to the Tuamotus and Austral islands, north to the Ryukyu and Hawaiian islands, south to New Caledonia, and in the eastern Pacific from Costa Rica, Panama and the Galapagos Islands. They can be found at depths as deep as 150 m (500 ft.). Yellow-edged morays can reach a length of up to 240 cm. (7.9 ft.) and are suitable only for very large aquariums.

Maintenance difficulty:    The Yellowhead Moray Eel, Dark-spotted Eel, or Fimbriated Moray Eel is easy to keep. Most eels are very hardy and readily eat all kinds of live and meaty foods.

Maintenance:    Feed all kinds of live fish and meaty foods. Use a poker if necessary at first to place the food right in front of their mouth. Don't worry if it doesn't eat for a while at first, they can go for several weeks without food (and often do).

I currently have 12" Fimbriated Moray living in a reef tank. I have been very lucky to not have any major incidents.

Make sure you have proper hiding places in at least 2 in different parts of the tank.

Fish in my tank include: Sohal/Yellow/Kole/Naso Tangs, Cherry Grouper, Green Bird Wrasse, Speckled Hawkfish.

Also, the eel loves the cleaner shrimp station. Lets him go all over and inside his mouth.

I have only had him for a short time, but so far so good.

I have a Sulphur Head Moray Eel (different coloration of a Yellow Headed Moray) and a undulate trigger fish (very aggresive), When they first entered my tank they tried to kill my resident Snowflake eel numerous times, especially the suplhur head (made the snowflake bleed many times). I eventually had to buy a new tank to put the Snowflake into. Then after a couple months, i put a decent size voliton Lionfish in the tank with them. During the FIRST Night, the eel (Nasty Nate) ripped the lionfish in half and ate everything up to his gills... A Very expensive mistake... The sulphur head will not attack the Triggerfish (Squirrel Master), in fact he will occasionally attack the eel. So, now I have what I call a Predator Tank. I throw poor little unsuspecting goldfish and mollies in there and watch them get devoured in just seconds! (The mollies give a much better fighting chance because they like salty water and are much more mobile.)

I purchased a fimbriated moray a month ago. Tankmates: four 6 inch columbian sharks, a 5 inch sailfin tang, two yellow mimic tangs, and a volitans lionfish. Within 24 hours, one of the sharks was gone, and that solved the problem of what i was going to feed it ($3.98 each)... The lionfish and the moray seem to have a polite respect for eachother. And the mimics and the sailfin try to harrass the moray, competing for hiding places. I ran out of decent sized sharks and started feeding the eel medium rosys, 3 or 4 at a time, what a time I had trying to keep the lionfish from eating itself to death while the eel fed. The sailfin succumbed to the moray a short while after, and the larger columbians were rescued and put in a brackish water tank. The mimics continue to press their luck, so far this moray has cost me $70 in fish, and is gonna cost me another $120, but at least it will be well fed!!

Our darn yellow-edged moray eel just ate the volitan lionfish that has been in the same tank with him for well over a year now! The eel is always well fed, so I don't know what his problem was today. It was a pretty large lion too! He left no evidence behind. We came home and the lion is nowhere to be found..... and Mr. Eel seems to not be hungry for his jumbo shrimp today.
