Do you still have the 29 listed in your profile? Achilles tangs are very difficult, prone to ich and need a big(ger) tank... They sure are beautiful. If you have a larger tank now then you may consider a white cheek. They're a little less fragile and IMO
EDIT: I see from your other thread that you've just upgraded tanks... I'd personally still steer clear of the achilles in favor of the white cheek, but I'm glad to see that it would be going into a 75. I haven't checked their space needs, but I'm sure the 75 is much better suited than the 29!
