Frustrated with the tank now what...

Redoing aquascape works for me, add a second yellow tang and they were fighting at the point that the new one was hiding beyond a rock for a week or 2, I had to target feed the poor guy, so I move everything on my tank and now they swim together all the time,is crazy but that worked for me...

Sadly I think I have found the problem...the 6 line has started to be aggressive towards my larger fish, trying to chase them around the tank. I think the tangs find it fun because they seem to play along for a bit but when they are done they turn and stand ground. Seems he may have to go only problem is catching the little bugger...
