Neoglyphidodon

Neoglyphidodon crossi

Allen 1991

Cross's Damselfish

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Western Pacific Ocean: Indo-Malayan Archipelago, mainly the Sulawesi and Molucca Islands.

Size: 5 inches (12 cm)

Natural Environment: Inhabits areas of rich coral growths on inshore reefs at depths between 3 to about 15 feet (1 – 5 m) and mainly feeds on algae and benthic invertebrates.

General Husbandry: Occasionally seen the trade, with the juvenile quite attractive having a reddish orange body, with the pelvic and anal fins the same color. There’s also a blue horizontal line from above the eye to the caudal fin. As it grows into adulthood, it loses its bright colors and overall, becomes dark brown.

Juvenile can be quite feisty, but as it grows into adulthood, they become extremely aggressive and must be housed with very aggressive tankmates, e.g., dottybacks, large angelfishes and surgeonfishes, and triggerfishes.

As to diet, a meaty diet, e.g., live fortified brine shrimp and/or finely chopped various frozen or fresh meaty foods such as mysis, squid, fish flesh, shrimp, clam and plant material, e.g., flake foods, especially those containing Spirulina should be offered several times daily.
