This species is known to jump out of open aquaria.
Since these fish are very shy, there are difficulties feeding them at first as they are reluctant to come out of their holes.
Most aquarists report however, that once they appear, they eat well.
One must make certain that there are no aggressive fish in the aquarium and they should not be kept with creatures which dig into the sandy bottom.
It is obvious that these fish must have as short a journey to their final aquarium as possible, as they do not normally have the optimum conditions in the petshop.
This species ought to be kept in a group of at least three.
There is a greater chance of success with this species if one can supply a living feed to allow it to adapt to the tank.
This fish requires feeding several times a day, especially when newly added.
When the fish can find its natural food in the aquarium it requires less frequent feeding.
This species must be kept in an aquarium with at least a 20 cm layer of fine sand.
The layer should resemble the length of the fish.
If necessary topped with another layer if the sand swirls round too much.
Eels are a large family, but mainly the subfamily, Garden eel (Heterocongrinae) are relevant in relation to aquaria.
Garden eels live together in groups. They require enough sand in the aquarium substrate to make their small but deep holes, also the more one wishes to keep the larger the sand surface needs to be.
The minimum number kept, should be 3, the optimum is between 6 and 10. Each eel however, needs at least an area of 12 by 12 inch (30 by 30 cm).
They eat zooplankton from the water column, which is difficult to maintain in an aquarium. At first one needs to have live Artemia and preferably a healthy population of zooplankton. Later on they can be fed with frozen foods, provided this can be fed in such a manner that it floats gently past the eels so it can be caught.
|Distribution||Indo-Pacific: Red Sea and East Africa to the Society Islands, north to the Ryukyu and the Ogasawara islands, south to northwestern Australia and New Caledonia; throughout Micronesia (Ref. 1602).|

"Minimum volume" indicates the size of the tank needed to house this species under optimal conditions.
This is based on a medium size animal, which you want to keep for several years.
It might be possible to keep smaller specimens for a limited period in a smaller tank. A larger tank might be needed for fully-grown specimens.
"Hardiness" indicates how resistant this species is to disease and how well i tolerates bad conditions in general.
Some species doesn't handle transportation very well, but that doesn't mean that the species isn't hardy under the right conditions.
In this case, a "normal" aquarium is a reef aquarium with mixed corals or a fish only aquarium with an approximately salinity of 1.026 (sg) and a temperature close to 26°C.
Species requiring more than a 4000-liter tank are considered not suitable for home aquarium.
Special aquariums may cover tanks with low salinity, sub-tropical temperature, deep sand bed, sea grass etc.
Always reef safe: No sources indicate that this species will harm corals or other invertebrates.
Often reef safe: Only a few aquarists has reported problems keeping this species with corals and other invertebrates.
Reef safe with caution: This species may be a threat to some types of invertebrates.
Reef safe with luck: Most specimens will harm corals and/or other invertebrates, but you might be lucky.
Not reef safe: This species is a threat to most corals and/or other invertebrates.
