Have you not already got a thread on this subject.

Correct me if I am wrong does a Vision 260 not hold 260 litres before any rock goes in???? Is it not also only just over a metre long???

Scott Michael recommends a minimum of 285l for the yellow Tang and 380litres for the Powder Blue I think.

May be worth getting yourself a copy of one of the two pocket expert books written by Scott Michael before buying anymore fish. sounds like you may need to change LFS as well.

the tank is just over 4ft long, 18inces wide, 25inces tall. i have got a post on this in reefs but info conflicting

IMO you may just get away with the Yellow but your tank is not suitable for the Powder Blue.

powde blue will get too big for your tank, just a matter of time
you could take it back to your LFS and get a dwarf angelfish

Not enough room for a Powder Blue in my opinion

one tang only or they will cause each other stress. It is better you add both at the same time, but even when you will probably get aggro.

I just bought a powdr blue and instead of a yellow tang I think I will buy a long nose yellow butterfly to save community problems. Powder blues are very territorial as clown tangs and others of the same genus i.e. Acanthurus see the Blue planet by David Attenborough about the PBT.

after a tank change from a 300 where my pb and regal where the best of mates to a 400 the pb changed into bully mark1 after a couple of weeks, its taken a fair few weeks from then for him to calm down again, the regals slashed him across the face which took the agression away for a couple of days before returning, now its relative peace in the tank again

personally if you have a lfs that advised you to get a pb in a 240 i would be seriously looking else where for one as the advice tendered was not good
