Hi everyone, I’m looking for some help identifying the Dino’s that are in the pictures attached. At least I believe they are Dino’s. I have seen similar pictures that allude them to being either Coolio or amphidinium but they don’t seem to match exactly. Can anyone help me in IDing these and the best course of action to eradicate? They are mostly on the sand but have seen them attach/bother my Duncan coral causing it to contract and I’m starting to see tissue receding. Thank you!
