The Niger triggerfish is not to be considered reef safe. It eats ornamental shrimp and other invertebrates and will try to rearrange everything in the aquarium which can damage and/or knock over corals. It is possible to keep several in the same aquarium as long as all of them are introduced to the aquarium at the same time. They can be kept in community aquariums with other larger fish that are not too timid. They should never be kept with small fish as they may eat it.


Not yet tank bred
