If the intention of the aquarist is to breed this species, then it must be done in a marine aquarium, as breeding likely does not take place within freshwater. Like all moray eels, this species does not like to be confined in a tank and it will try to escape. Therefore, the whole top of the aquarium must be secured with a tight-fitting lid.
In most aquarium tanks, the fish are at high concentrations and the volume of water is limited. This means that communicable diseases can spread rapidly to most or all fish in a tank. An improper nitrogen cycle , inappropriate aquarium plants and potentially harmful freshwater invertebrates can directly harm or add to the stresses on ornamental ...
The following is a list of aquarium diseases. Aquarium fish are often susceptible to numerous diseases, due to the artificially limited and concentrated environment. New fish can sometimes introduce diseases to aquaria, and these can be difficult to diagnose and treat. Most fish diseases are also aggravated when the fish is stressed.
Velvet disease (also called gold-dust, rust and coral disease) is a fish disease caused by dinoflagellate parasites of the genera Amyloodinium in marine fish, and Oodinium in freshwater fish. The disease gives infected organisms a dusty, brownish-gold color. The disease occurs most commonly in tropical fish, and to a lesser extent, marine ...

Ich sometimes limits infection to the gills and the only sign that a fish is infected is an increase in breathing rate, lethargy, and clamped fins. If left untreated, in a small volume of water such as an aquarium the infected fish can quickly succumb to the rapidly multiplying parasites.
