Overview

The white-spotted spiny eel is a large, solitary eel for a rocky, sand-bottomed tank. It is best with a little experience.

Did you know

The white-spotted spiny eel's scientific name, alboguttatus, means white-spotted, from albus for white and guttatus for speckled. The hobby calls it the starlight eel, for the scatter of small round pale spots over its dark brown body and fins. No two individuals wear quite the same arrangement of points.

Caring for the white-spotted spiny eel

Keep the white-spotted spiny eel in a tank of 106 gal (400 L) or larger, since it grows large. Give it a sand base, piled stone, pipe hides and plenty of hard cover to shelter in. Fit a heavy, close-fitting lid.

Keep the water soft to neutral, at 73 to 82°F (23 to 28°C) and a pH of 6.0 to 7.5. Keep conditions clean and stable, with moderate, well-oxygenated flow. By day it buries in sand or slips into rock crevices, and it comes out at night to forage. Feed meaty foods in the evening, such as earthworm, mussel, and frozen bloodworm, krill and prawn.

Keep it on its own, as it will drive off others of its kind in a shared tank. It is peaceful with tank mates too large to eat but will take small fish. Choose robust, calm companions rather than tiny or delicate ones. Spawning in aquariums has not been reported.
