Thanks so much!!!!! I volunteer at my local aquarium so it's rly nice to hear my tank is cool too haha. And he is very reef safe he actually will eat certain pests off the corals. He mainly hunts copepods in my tank but I also try to spot feed him some small pieces of mysis and cyclopees. But he really just mainly eats copepods, he's always hunting looking in my rocks. But a very cool addition sometimes he surfs the current too!
