Niger Trigger

Niger Trigger

The Niger Trigger is most certainly a very impressive fish for the home aquarium as it holds physical attributes alike no other fish. The colouration of this fish varies greatly, and range from blue, green to purple. This fish also holds a striking electric blue highlight on the tail lobes and fins, which really makes it stand out. As this fish matures into a fully grown adult, it will develop into a darker purple colour with a lighter blue or green highlight around their face, and will even develop bright red teeth. 

This trigger requires a 500 litre or larger tank that includes a variety of liverock and caves. However, it should also be noted if this fish does not like the current rock work in your tank it will almost certainly rearrange the rock itself. This fish should not just be purchased without researching beforehand, as it needs to be housed with other aggressive or large fish to stop it from bullying any peaceful fish. 

This fish is extremely territorial and if planning to home, it needs to be the last fish added. As once it has discovered its territory, it may be very aggressive and defend the tank from new tank members. Additionally, the Clown Trigger will erect its dorsal spine when impressing an opponent or as a defence mechanism. 

This fish most certainly needs to be offered a wide range of meaty foods. These can range from small fish, shrimp, squid, clams and hard shelled foods to grind down their ever growing teeth.

  1. I bought a Trigger a few months back. This fish is very graceful when it swims and is friendly towards me. I really liked him until I came home one day and he had killed my pair of Clownfish, my Domino Damsel, and my Horseshoe Crab. He didn’t bother my Yellow Tang or Hermit Crab. I quickly made a divider. Be very careful about adding this fish because they may not seem very aggressive at first but they really can be.

  2. This is one of the nicest Triggers that I have ever owned. He learned some bad manners and became violent from watching my Undulated. He was show quality and had beautiful teeth but became very aggressive toward my Lion and Grouper so I gave him up. Great fish to watch and will feed from your hand. Thing was a tank, and could hold its own against even eels. Great choice for an aggressive setup.

  3. I have known many to say these are aggressive fish, but I had absolutely no issues with mine at all. I would have actually considered it peaceful, I guess it really is trial and error with triggers.
