Tank diminsion and stocking questions for a 150g

[BBN]

I saw a 150 gallon tank at Petsmart and I believe it as 4' wide about 3' high and 2'(?) depth front to back. I was wondering if this is going to be more than enough room to support a Blue Hippo(Regal) Tang. I have a Yellow Tang also and he's gotten along great with the Blue Hippo. My question is would I be pushing it if I added a couple more Tangs of one of these? I think seeing about 3 of one of these species is the coolest thing. My plan is a sand substrate and about 100-125 pounds of rock with coral mixed in also. I was wondering if it would be OK to have more then one of these species in a 150. Also, should I look for a 150 long instead of this one or will this be enough room for my Tangs to get around? Will the sand stay undisturbed with powerheads running?


Here what I have and what I'd like to add:
I have:
Yellow Tang
Blue Hippo Tang
Yellow Tail Damsel
Mandarin Goby
Lawnmower Blennie

I'd like to add:
a couple more of one of these breeds of tangs
a clown of some sort
Maybe some more Damsels

What do yall think? Could I add any or all of these on my wish list? Thanks.

I would urge you to use extreme caution with the tangs. I have a 55 gallon set up and had a yellow tang and a brown tang, both purhased young". Everything went along jsut fine till they started growning up and relaised that hey were both tangs! W.W. III I ended up buying another tank to keep both of them alive. Damsel can be agresive but, so can l.m.b's I though about getting one till I did some research on it and made a post here. Apparently some of them are fine and some of them go loco for no reason what so ever. The Mandrin should be fine if you give your tank around a year to get enough copepods for him to eat. Yes, there are some foods out there that are supposedly good for em and you can supposedly train them to other foods. I wouldn't risk it though it apparently has a very poor success rate.
Not trying to rain on your parade though as far as I know everything else shoudl be alright.
hope this helps

Thanks Chris. I watch these Tangs everyday to watch their interaction. If it does come to fist-a-cuffs I'll have to make the tough decision to send one to the LFS.:sad
