I've collected and kept it, it does ok, but it doesn't really like captivity. Almost all of them assume the freight pattern and never get the pretty yellow color back, no matter how long and how well they seem to adapt. The pattern is like the night pattern, the yellow fades and the body has sort of a sooty color over the faded yellow and the blue stripes lighten up. I kept the one I had for almost 3 years and it never colored up fully in that time. Other then color it was a great fieh, active and peaceful, never bothering any other tankmates. I fed it a mix of frozen and pellets as well as fresh scallops and when the sargassum comes in I collect the small shrimp and feed all my fish them live.
