Ok, so how much light would be enough for a BTA.
I am currently running a 135 gal with a 48" 110wx2 VHO...
I have a pair of false percs along with a blue and yellow tang
and a nice auriga butterfly. All seem quite happy with each
other by the way, nobody seems to bother anyone at all, the
percs seem defenately a pair as they are inseparable.
Thanks for any advice in advance.
