Mindless cr*p deleted

My Yellow Tang developed this when a) I first introduced it (it also
picked up a dose of Ich) and b) after I stressed it out after adding
more live rock while it was in the tank (it was impossible to catch).
On both occasions the red slowly faded over the next 2 - 3 weeks and
the Tang showed no ill effects. Change the water if you really want
but I don't think it necessary - it's almost like a bruise that just
fades away.

This subject is also mentioned on the WetWebMedia website and on Reef
Central - a forum 100 times better than this one.
