The Niger Trigger, also known as the Redtooth Trigger, is a vibrant and active fish ideal for large marine aquariums of 180 gallons or more. Its colors range from purple to blue-green, shifting with lighting and mood, and adults feature distinctive bright red teeth. This species requires rock structures for hiding and may rearrange its environment. It produces grunting sounds and thrives in aggressive, fish-only setups. A varied diet of meaty foods like squid, krill, clams, small fish, and hard-shelled shrimp is essential to maintain its dental health.
