Thoughts on clown tang in 180?

[xtreme]

As Kien mentioned they are a tricky fish to keep alive long term. If you do end up getting one to stay healthy in your tank I think you will have a very hard time adding a powder blue and orange shoulder once the clown is established. Acanthurus tangs generally do not get along very well. I don't think your tank is big enough for 3 acanthurus tangs or 7 tangs in total. I have 6 tangs in my 280 and I already foresee them outgrowing the tank down the road. I hate to sound like the TP, but IMO I don't think your tang list will work.
