Acan tissue loss: causes and solutions

[Flynxide]

I've had this acan for 2-3 years with zero issues. Just recently moved my 38 gallon tank to a new 40 breeder, everything else is thriving. This spot on my acan showed up a few days ago and it's growing daily. Initially I thought it might be brown jelly disease - there's some brownish tissue where the coral is missing. Hard to see in the photo, but that's the best I could get without taking it off the rock. If it is brown jelly, I know I'll have to cut the healthy coral away. But could it be something else? I really don't want to lose this acan.

Have you checked your water parameters to ensure everything is in line? I've noticed my Acan corals are particularly sensitive to low Alkalinity and low Magnesium levels. With my large Derasa clam and recent Maxima addition, they're putting a strain on my parameters. After correcting the imbalance, my Acan corals showed significant improvement, and some of my other LPS corals looked even better than before.

It's possible the coral was stung or damaged during the move. Maybe it came into contact with another coral or a rock, causing an injury that's now infected. In that case, a coral dip and/or fragging might be necessary to address the issue.

I've had my share of ups and downs with Acan corals. I lost my first one due to unknown reasons - it just started wasting away despite growing rapidly beforehand. It looked healthy and puffed up like yours until it suddenly melted away. I tried dips and fragging, but they didn't help. I even attempted hydrogen peroxide dips, which did help save a wall hammer from brown jelly (although I lost it about a year later for unknown reasons).

Hopefully, others will be able to offer some insight, as I'm not sure I've added anything new to the table.

Just wanted to check in, how's that Acan doing? Great looking coral btw

Thanks for the suggestions everyone. Parameters are pretty close to spot on. I did remove the acan and give it a good dip, just in case. I'm still not entirely sure what caused the issue, but I'm leaning towards it being related to the move from one tank to another. It's possible it got stung while in the bucket with other corals, or maybe the increased light exposure in the 40 breeder is taking a toll. I've got it under close observation for now, so we'll see how it goes from here. Appreciate the help.

Hey guys, having some trouble posting a new thread so I'm gonna jump in here. Been following for a while, first time posting. Got a 36g BF with a 20g sump, pretty standard setup - NO's-0, PO-0, NH-0, 500/1480 CALMAG, 8.3ph, 1.025. Using T5 lights, two 30-inch strips, four lights total. Tank's only a couple months old, but I've had some issues. Spent a lot of time and money on this setup, got live sand from an LFS, LR and media from a cycled tank for my DIY overhang drip filter system. LPS, SPS, and Softies are struggling, looks like copper toxicity but I know there's no copper. Not sure what else could be causing this or what to test for. Any help would be great, thanks.

I'm pretty diligent about dipping when acclimating, and I've got a UV running, so I'm inclined to think it's not bacterial or fungal that's the issue here. I've seen immediate tissue necrosis and zoos expelling, and it's usually game over within 24-48 hours.

I'm pretty sure I've seen this before, but I could be completely off base - you might need to have a certain number of posts under your belt or wait a bit before you can create a new thread.

Here is the Acan as of today. It does appear that tissue loss may have stopped after the dip. I'm keeping an eye on it. I now have this ugly bare skeleton section right in the middle of it. I hope if it recovers from this that new tissue will fill that spot. I did mount it a little lower down than where it was previously. I still wonder what was the cause of this issue as I have never had this happen to any of my Acans.

It's been opening up nicely at night and looking pretty good, so I'm hopeful. I think the iodine dip might have been the turning point, to be honest. I've always used Coral RX in the past, but I'm currently out of it. Still, I'm curious about what initially caused the issue - the dip didn't seem to bring anything out except for a bit of dead tissue.
