Ok well I have had another death and it was of course my beautiful half black mimic tang. Everything was good and then one morning he wasn't there. No symptoms of problems nothing just poof gone. When I added him in everything was fine then a few weeks later when I added in a tomato clown they kind of had it out a few times but both settled down. Now weeks later after everything is calm my tang is gone??? My first tang died of ick mainly because I was impatient and added him too soon but this guy was healthy eating and showed no signs of distress at all. I would think a predator got him but I haven't had a fish disappear since I took out the sally lightfoot months ago. I did find what appears to be a burrow under a rock but have never seen anything in it. I haven't added anything to the tank except for a few small zoo frags that I'm 100% sure didn't carry anything in with them. Only other thing added was a few peppermint shrimp and some very very small scarlet leg hermits. Could one of those tiny hermits be a killer??? They don't look big enough to even take on a pod and win. It really sucks because I love tangs and really want a tang but now I'm almost resigned to thinking tangs just aren't for me.
