The first photo is from 3.5 months ago when I first got this clownfish pair from LA's Divers Den. He was in my QT tank at this time where he spent 4 weeks in observation (not medicated). Second photo is from yesterday in my display tank. He otherwise seems very healthy and active, no flashing/heavy breathing and he has a great appetite. The white spot on his tail looks flush with the rest of his body, it is not raised in any way. Is it possible it's just how his markings have changed as he's grown? Just making sure I'm not overlooking anything obvious as how much it has grown does look concerning. Appreciate it!
