Not aggressive feeders. They grow slowly but are very peaceful. They do hide sometimes. Buy one more than you want as they come small. I kept mine separate until they ate better. I have mine in a tank with Tangs, Rabbitfish, and other smaller fish. Very peaceful.

The fish was shipped extremely well, and it was a perfect addition to my reef tank. I acclimated according to the instructions, and I have had no problems with any of the fish I have received. What more can you ask for? Cheaper then my local fish store and it was delivered to my front door the next day.

I have 3 of these I bought here and had shipped to MN this November. The arrived on a 21 degree day but after slow drip acclimation made it and swim lazily around my 40gal Reef Tank. They are a colorful addition to my tank and interesting to watch. I did not know before but do now that they are night foragers, so I will have to start dropping some pellets in at night. They do well when I feed the tank twice a day with Mysis Shrimp.

These two guys have become the guardians of my mini rank. Hovering over their tank mates and making quick bursts whenever they have somewhere to go. Really cool colors and they fed soon after introduction into the community. Mysis shrimp and varied flakes are consumed . They like to stay up at night and roam. Very peaceful little buddies.
