It’s never perfect

Hello from South Houston!

Im new to R2R, but have has reef aquariums for about 10 years now. Started with a 45g tank with HOB skimmer and a external filter until 2 tears ago and upgraded to a 90 show tank (short and wide) with a sump below the tank. My tank is mixed reef with only soft corals. I like to buy unique frags so I don’t usually know what they are and have had most good success. That being said, I seem to have trouble with some types of coral while other grow crazy. Fish are never a problem, usually living quite long and sometimes getting to big for the tank (give them back to the local store). My question is since I really don’t know what the name of some of the corals, if I posted a picture on this website of the coral I’m having trouble with, are their users experienced enough to 1) identify the coral, and 2) help name figure out why the coral isn’t doing well? And yes, I measure many parameters and add chemicals as needed (pH, Mg, NO, temp, salt, Kh, PO, Ca); I doRO/DI water changes every week (no refugium), so I’m thinking it must something that I don’t know about. THANKS!!

Just out of curiosity, what are your parameters? Maybe we can zero in on a possibility. Very nice looking tank. Do you run carbon? One thing I see is you have a fair amount of leathers & they are notorious for coral warfare.

Yeah, those toadstools are gonna go. They’re really a pain and tend to nuture algae, bth around them and on the glass. A few others identified the coral in question as an Acan (thanks all) and I seem to not be able to get them to live/grow. OK, my parameters (from memory, measured a few days ago) Mg~1300, PO<.1, NO~5, Na- 34, KH~10, Temp-77, Amomia-0, Ca~400, Ph~8
 
Welcome! I also have a 90 that is currently undergoing a reboot (definitely NOT a show tank at the moment). It sounds like you already have the ID on the corals, but I'll tell you a little trick I started using. I was terrible about gluing my frags to the rock and then snapping them off to move them around. I glue mine to a piece of rubble now, just for that purpose. I've found acans to be particularly picky about where they want to be. I'm currently moving some now to find the sweet spot with better light/flow.

Thank for the tip, I'll give it a try.

I hope it works out for you. My biggest regret with previous acans was I decided where they should go instead of listening to them....well, I guess watching them. Since I moved my current acan frag this morning, I can already see it's much more puffy with extension.
