You know what sir,
Upon closer inspection it looks as if the orange clown has something stuck in him. Like a tiny white spiky thing????

Probably just a mucus plug. Ich is round and not spiky. A sting from a bristleworm can leave a tiny spike sticking out, but coral stings don’t.

Is a post I made about a week ago I posted about these tiny tunnels being formed in the sand, a lot of people suggest it could be bristle worms.
