Hi all, I've had this Tomini tang for about a month and he's been perfectly happy. A little shy at first but now it swims around the tank like it owns it. Tonight I found some white spots on its face. Looking around online it seems like it might be scratches from swimming around? I'm not sure I agree with this. I've recently added a cleaner shrimp, conch, and 2 snails. I also have a 6 line Wrasse, lawn mower blenny, and two clowns in the tank. Yesterday I added 5 small coral frags 2 zoanthids, 1 candy cane, one red war coral and a sympodium. Does anyone have any thoughts on what this might be?
