I went on a trip to Hawaii last summer, and the last morning there I went to some tide pools and managed to get some pictures of them. In one of the pictures was a convict tang, scroll algae, and what I've identified as a black spot sergeant fish. Now, I'm looking to stock a 175 gallon reef tank and I thought it would be really cool to be able to recreate that scene. The convict tang shouldn't be too hard to find. Scroll algae would be a bit of a challenge. The sergeant fish, however, I have not found much information on at all. I know it is a type of damselfish and reaches around 9 inches in length, but that's about all I've found. With that, I'm wondering is this fish reef safe, how to properly care for it, and where on Earth can I find this fish short of making another trip back to Hawaii and flying it back to the states. Any and all information would be very helpful.
