Can someone help me ID this please. This is the best pic I could get of it before it went back into the rocks. It is black with a white spot on it, it looks almost like a stingray of some sort without the long tail.
Probably a Shield Limpet. Does it look like this:
Yes very similar. I have seen one in the tank before but had no idea where to start trying to identify it. Thanks Mark, now of to do some research
Have seen orange variants of this limpet consuming soft coral and various zoanthids/palythoa. The black one is confirmed to do the same per Spung's "Reef Invertebrates". Good luck prying that thing out!
I've seen these in other reef tanks and they were considered a good guy. I got one but didn't get to enjoy free offspring, something I was counting on. It's a grazer and will eat algae. If you do want to extract it from your reef, it can live in your refugium and keep that zone cleaner.
