i have a jeweled moray (aka mexican dragon) and it's my personal favorite (aside from hawaiian dragons)...here is some more info since they aren't as common as sfe's and some other species:
The Jeweled Moray Eel originates from the shorelines of the Eastern Pacific, from the Gulf of California and south throughout Central America. They are one of the smaller Moray Eels, only attaining a maximum size of 24 inches. They are black with beautiful white markings. As a juvenile, these eels are brown with gold spots. This species adapts readily to aquarium life, and does not require a large amount of space.
This is a very hardy eel, but is an escape artist, and requires a tightly sealed aquarium. A 50-gallon or larger aquarium with plenty of live rock for hiding is ideal for the Jeweled Moray. Most of the eels that are lost in an aquarium are due to poorly sealed tanks. These eels are very aggressive in the aquarium, and will eat any fish, crustacean or other eel that it can swallow. Do not house more than one of this species in the aquarium, unless the aquarium is larger than 120 gallons, and the eels are of the same size and acclimated at the same time.
The Jeweled Eel is a nocturnal predator, ambushing fish and crustaceans. In the aquarium it will learn to feed during the daylight hours, and it will take frozen or freeze-dried krill, fish, shrimp, and most meaty foods. It can be taught to hand feed, although this should be done with caution, as it can inflict a painful bite.
i've had mine for about 5-6 years now and he seems to have topped out at about 18-20 inches...to me it's a little more interesting looking than the sfe, but thats just me...he shares his tank with a lion and a mean little damsel who was kicked out of the other tank about a month ago for killing his tank mates...
hth,
