I just purchased some aussie acans and was curious on placement and maybe predators. I have a 90 gallon tank (upgrading soon due to a few tangs) with 2 250 watt 14k ushio bulbs and 2 96 watt actinics. The fish that I am a little worried about is the six line wrasse. My tank is mostly sps with a couple of zoas, a yellow leather and a rose anenome that he does not bother but I am new to lps and just want to make sure he wont nip at them.
