The Niger Triggerfish is a stunning addition to my tank. The coloration is vivid and the streamers are impressive. I’ve had it for three months and it’s still active and healthy. Only a 75-gallon tank was needed, which fits my setup perfectly.
Kevin Reid –
Great color and movement. I was cautious about keeping it with corals, but it hasn’t damaged any. It’s semi-aggressive, but not overly so. The streamers are long and beautiful. I recommend it for beginner reef keepers with proper tank size.
