What I am actually trying to figure out here guys is an idea of what this acro is so that I can better it's survival. I am not really interested in the fancy names, I just want to do the best I can to give it the best quality of life in my tank that I can. I can't do that without some idea of what it is. When I first got this acro, it was a piece that was damaged off of an Aussie Acro at an LFS and they didn't really know what it was. They just said it was some sort of Yellow Acro. Since then it grew over itself and the damaged areas and has encrusted at the base and keeps encrusting down the rock now but it has not really branched except for a couple of bumps and I am afraid it is losing its corallites but the polyps themselves are very large. I am wondering if the polyps being so large and out most of the time are actually keeping the zooxanthellae from staying inside the coral or something. I have only ever had LED lights, all my params are good and everything else is growing great in my tank including other acro's. This acro has been growing for at least 6 months now without much success in my opinion. It is at a high position in my 90 gallon tank. Also, I believe this Acro is wild as my other Acro's were pretty established from other tanks. I am new to Acro's.
