I was cleaning my lights when I thought I saw a fish in my overflow. It was my yellow belly regal tang. I probably haven’t saw him for a better part of a year. His color has faded and looks pretty beat up but he is swimming around now and eating like a pig. He is around 6 inches long , pretty thin and having to swim around two pipes in an overflow for so long having to eat whatever flowed into it is pretty amazing how he survived.
