Class: Actinopterygii (ray-finned fishes)

Max. size: 38.0 cm/ 14 inches

Environment: Fresh and brackish waters

Origin: Common throughout south-east Asia

Temperament: Aside from eating small fish when larger, very peaceful, may even be picked on by more robust tank mates.

Company: Being predators they should only be combined with fish that are over 3 inches, smaller fish will be eaten.

Water parameters: temperature 23-28°C / 73-82° F; pH 6.5 - 7.5

Aquarium setup: Macrognathus aculeatus(Lesser spiny eel) is he smallest of the commonly seen spiny eels (tyre track and fire eels being the others) and it is more suitable for home aquariums than its giant relatives, a minimum of a 36 inches tank should be used to house this fish. Offer a sand substrate since the fish likes to burrow, plants are best left out since the eel/s will continually uproot them. They are not fussy of water parameters but the extremes of hardness and pH should be avoided, neutral water is best.

Feeding: Like with all eels feeding can be difficult, most eels will only accept live foods at first so try bloodworms, daphnia, glassworm, brineshrimp and black mosquito larvea, larger specimens should also take river/ghost shrimp. Once the eel is feeding confidently live foods can be swapped for frozen.
