Help with safe reef fish

[Saltlife757]

I have a 4 month old 180 gallon (soon to be reef tank) aquarium. MY live stock is all about the same size (2-3 inches) and consists of a blue hippo tang, yellow tang, 4 chromis, and 2 black iced clown fish. I also have a frogspawn and GSP. Everything is going very well. The water parameters couldn't be better, all the fish eat, sleep, and swim in harmony. Taking things slow has definitely payed off!!

My question is about adding new fish. I would love to have 1 or 2 more tangs, preferably a powder blue or Achilles. From my research, I cant really find a definite answer about why these fish are difficult to keep? I know they are ich prone, but so are my yellow and hippo.

IF not tangs, what other first look really great in a reef tank?

I understand that you're tank is sufficient for a tang (or two), but I think I'd stop there with the tangs. You may be pushing it with fish that can/will grow to be quite large.

What about something like a damsel, yellow watchman goby, etc?

Here's what LiveAquaria has to say about the Achilles Tang, "A 180 gallon aquarium or larger is necessary to provide plenty of swimming room,and these fishes require strong water flow as they are normally found in surge zones. It is aggressive towards other Tangs and Surgeonfish, but peaceful with other fish."

Powder Blue Tangs and Achilles Tangs are much more prone to ich and other diseases than their other cousins. Powder Blues are also super aggressive primarily to other tangs but really to any other fish in their aquarium, beautiful fish but real jerks. Achilles Surgeonfish are also super aggressive towards other tangs although much less aggressive towards other fish, because they live in very high flow surge parts of the reef, they also require a high water flow tank.
