Pinktail Triggerfish: The Semi-Aggressive Beauty
The Pinktail Triggerfish (Melichthys vidua), also commonly known as the Red-Tailed Triggerfish or Whitetailed Triggerfish, is one of the more docile and reef-compatible members of the triggerfish family. It is admired for its striking emerald-green to dark body, bright yellow accents, and its namesake pale pink to reddish-pink tail fin.
This species is an active, fast-swimming fish that can reach up to 16 inches in length. Due to its large adult size and need for swimming space, the Pinktail Triggerfish requires a minimum aquarium size of 125-180 gallons or more. Although often less destructive than other triggers, the tank must feature plenty of caves and structures for shelter and hiding.

I’ve had my Pinktail Triggerfish for six months now and it’s been very active and healthy. The tank has plenty of caves and it uses them often. It doesn’t damage corals like some other triggerfish, which is a relief. The coloration is vibrant and it looks stunning in the tank.

The fish arrived healthy and has adapted well to the 150-gallon tank. It swims fast and enjoys the open space. I appreciate the detailed care notes included. It’s not aggressive, just curious and active.

This fish is a great addition to a reef setup. It’s calm compared to other triggerfish and doesn’t nip at corals. The pink tail stands out beautifully in the green background. I’m happy with the purchase.
