Appearance and identification

Its bold blotches contrast with the finer X-shaped marks of Mugilogobius myxodermus. It uses shells; not every goby does.

Floor and movement space

Provide stable stones, root-like cover and several retreats, optionally clean empty shells. Leave feeding space.

Aquarium environment

Plants can divide resting areas among stones and roots. Keep accessible feeding locations; it needs alkaline water.

Diet and feeding

Eats tiny snails. Confirm each fish feeds.

Same-species behaviour

Shells provide shelter, but eggs may also be laid on exposed surfaces.

Compatibility limits

Give food access and retreats; not all lake fishes are compatible.
