The Niger Trigger


A year or two ago I got my first trigger and it was a Niger Trigger. I loved it but my partner didn’t, so I loved it more!


Triggers are truly unique in the way they look and swim. They are a very active fish that loves to swim around and move the rock work around from time to time.

However caution must be taken when housing with other fish as they tend to be aggressive. As a result of this a fish-only aquarium with no coral is recommended.




Tank Size

180 gallons as they love to swim and grow large


Care Level




Aggressive – triggers are generally aggressive towards other tank mates and are best suited to a predator tank


Max Size

1 foot


Reef Safe

No – They will munch on corals if given the chance and rearrange the rock work.



The Niger Trigger can go from purple, to blue, to blue/green throughout the day and have a bright blue streak on the tips of their fins. As they grow they develop bright red teeth.




Carnivorous – The Niger Trigger fish needs a varied diet of meaty foods including; squid, krill, clams, small fish and hard shelled shrimp to help wear down their ever growing teeth.
