AKA (freshwater) Morayeel is not freshwater at all. Should be a high brackish to full salt to live a love heathy life. Will not live long in freshwater. There is some exp. but most likely just luck and the eel is not heathy.
Gets large 2'+ so will need a nice size tank that is well coverd. If useing HOB filters,will need to run water low to keep a space so the eel wont be able to swim up and in the filter

Warning! Thomas Flörkemeier (e-mail:
floerki@yahoo.de) reports that, in his experience at least one moray eel, Gymnothorax tile, is so intolerant of copper-based medications that they are killed by doses that are routinely used to treat aquarium fishes. Aquarists keeping freshwater morays should consider this when using many of the commercial medications and act accordingly.
Warning! Moray eels have sharp teeth and a strong bite; while not aggressive, they should be treated with respect.
Although traded as freshwater fishes, these fishes really need moderately brackish water to do well, and most probably prefer salinities approach normal seawater. As such, they may mix well with scats, monos, and other large, brackish water fish. Usually they ignore their tankmates, but some specimens do become aggressively predatory. The safest approach is to keep a small group of these eels by themselves in a single-species aquarium. A lair of some sort is essential, such as a flowerpot or cave built from rocks. Providing they have adequate space, morays are very tolerant of one another and in fact seem to be happier in small groups and will spend more time on view instead of hiding.
Morays often need to be trained to accept dead food. One way is to attach food items to cotton thread and dangle this in front of the eel, rather as if you were fishing with rod and line. Prawns, fish, squid, and mussels all make suitable foods. Move the bait about a bit, and the moray will generally catch on. If the moray refuses dead food for a while, earthworms and river shrimps make good treats, and in the case of Echidna rhodochilus, can be used as a staple without problems. Bear in mind that morays are largely nocturnal and hunt by smell rather than sight, so the evening is likely to be the best time to feed them.
Gymnothorax tile is another species seen in home aquaria. It is pinkish-grey in colour and covered in many tiny cream spots. The biology of this species is not fully understood but it is believed to be anadromous, meaning that it inhabits brackish and marine waters as an adult but breeds in brackish or fresh water. It is a large fish, potentially reaching 60 cm (24 inches) in length.
