should I buy powder blue???

That is one big Kole tang.

 

powder blue

Well I have to say if you have it down with fish and you have done your research I say your okay. However if your are thinking of getting one make sure he is the last fish in the tank. I had a powder brown who was doing awesome ate like a pig was healthy, but when I added my coral beauty he almost killed it. Powders are very aggressive and territorial so make sure that he is the last one. As far as health give him algae like every other day, keep him mostly on frozen if you can it's healthier and you should be good.

 

just for input...
I have a powder blue tang. It is over 6 years old. It got ick a couple times and one time it got it pretty bad. I bought a couple cleaner wrasse to make a "cleaning station" and they got ick from cleaning the tang and they died. I get two cleaner shrimp and the made a little cleaning station out of a ledge on the rocks where I built a cave. My PB would go to them and lay there while they picked chunks from him. The first time (the time I bought the CS for) they picked a chunk aound the PB's eye down to the bone and he looked pretty beat up but I was totally shocked to see him pull through and is still pretty as ever! My only problem is it only eats mysis shrimp. It won't eat those sea weed things or anything else but he(it) is still grazing and kicking butt. He(it) is in a 55 right now... soon to be 72 bow... and it doesn't nip at any corals. He'll do flips and just has a good ol time in there. I REALLY wish I could house it with a powder brown.

That's just my experience though. I want another 6-line but my neon goby keeps kicking them out of the tank. He even kicked my 8 line and my (new) cleaner wrasses >>> those shrimps died. To boot.. I bought another cleaner shrimp yesterday >>> NO WHERE TO BE FOUND! I know it was that goby! OOOOOO when I do my tank swap!

 

Long as ya have room for him, it would be great...If I had room I would go with the Powder Brown....I have a 55 and barely have room for my 70 lbs of rock....and 1 lonely fish

 

I personal have never had one but my friend had one & it was extremely aggressive to everything in the tank & it nearly killed the yellow tang. I'd be cautious in getting one of these and would suggest sticking to the hippo tang & i would think you be happy and would have better luck
