LOL Mr. X staying outta the stocking issue, LOVE it. hehe
I would in my opinion say you are overstocked. :-( Thats alot of bioload even for 110g. But if you can keep parameters steady and stable then good for you.
A 110g is a four foot tank or a five footer? My bigger concern would be the swim room for those tangs. I have a yellow and a blue in my 6 foot tank and they race back and forth all day long along with a tomini tang. I am in the process of going to a 180g most likely so i can give them a little more back to front room, it won't be much but any extra room for tangs is a good thing.
