Appearance and identification

Often sold as julii. Head spots versus a network pattern are only clues because patterns vary.

Floor and movement space

A 45 × 30 cm base is suggested; allow for adult group size, layout and foraging space.

Aquarium environment

Leave clean, smooth substrate and open foraging space.

Diet and feeding

Provide suitably sized sinking food and a varied diet; leftovers are not enough.

Same-species behaviour

Keep at least six.

Compatibility limits

Choose suitably sized peaceful companions; small shrimp may be eaten.
