can be used for decor, along with plastic plants if desired. |
| Compatibility | Semi-aggressive towards its own kind, and is therefore best kept in a group of 5-6 or more to spread out
the aggression. Generally ok with other similar sized brackish fishes such as Monos. |

| Sexing | Unknown |
| Breeding | Unknown, but only likely to occur in heavy brackish or marine conditions. |

Two colour forms of this species occur, known as the Green and Red scat. The red scat has been known as Scatophagus argus atromaculatus and
Scatophagus "rubrifrons", but it is not officially recognised as a separate species or subspecies.
