Blue Triggerfish
The Niger triggerfish aka Redtooth (ed) triggerfish is a popular aquarium fish and one of the few triggers that can be found in schools and that you can keep more than one of in the same aquarium. The species is quite common in the trade and if your local fish store doesn't have it in stock they should be able to order it for you. You can also order one yourself from one of the many online dealers sell marine aquarium fish. The Niger triggerfish can grow to be 20 in / 50 cm but seldom grow larger than 10 in / 25 cm in aquariums. They live to be about 10 years old. Their lifespan in the wild is even longer. The Niger triggerfish is a beautiful fish that can look a little different depending on mood. Usually the Niger triggerfish has a completely blue body. The further back on the body you look the softer blue it becomes. This fish can however sometimes display green color as well. The edges of the fins are bright blue. When they fish get excited, it can vocalize a grunting sound. The Niger triggerfish is usually not aggressive towards other fish species but can become aggressive with age. They are tolerant towards other Niger triggerfish and 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.
