I have been buying a few Acans lately ,,, nothing high $$$,, wanted to make sure my tank is going to keep Acans happy before I started getting some of the nice Acans ,,, I have been mounting them to my rock scape,, like you would a zoa frag as opposed to having a Acan Garden on my sand bed,, did I mess up doing this, will the Acan's in my tank be happy mounted to my rock scape? I am kinda just starting out with these Acans,,, none of my frags have increased in size (added new polyp growth) as a general rule,, I know each tank is different ,, how are Acans when it comes to adding new polyp growth?
