Description
The 3 Stripe Damsel is a small, vibrant saltwater fish that is popular in the aquarium hobby due to its hardiness and striking coloration. It has a deep blue body with three distinctive vertical white stripes.
Reef Safe
Yes, but they may nip at small-polyped stony corals and some soft corals.
Environment
This fish prefers tanks with plenty of hiding spots and open swimming areas. They are tolerant of a wide range of water conditions, making them a good choice for beginner aquarists.
Behavior
3 Stripe Damsels are territorial and can be aggressive, especially in smaller tanks. They can be kept in groups if the tank is large enough, but they will establish a pecking order. They are active swimmers and will often be seen darting around the tank.

Incredible aggressive, I have seen them nearly kill multiple fish, including a tang larger than they were that was in the tank first. Purchase at your own risk. Cool looking and active fish though.
