Acan Colony Dying...What is this?

[Falco]

Just noticed this morning one of my Acan colonies is dying out fast, not sure what's going on here. any suggestions? I am thinking I might have to pull it out and frag off the bad area to maybe stop from the whole colony from dying?

Thanks in advance for any help

Looks like it got stung by another coral. Anything nearby that could possibly reach it?

I thought of that at first but there are no other corals even close to that colony so not sure how that would be possible.

Do you have any peppermint shrimp? In an old tank I had they were always all over my acan colony at night and annoyed it to death bit by bit

just have a cleaner shrimp, no peps. Have snails, conchs and the cleaner. No crabs or stars

Any test results to check the water?

Could be bacterial. I would get some iodine based dip like seachem reef dip and give that coral a soak per directions.

temp - 78.4
Salinity - 35
Ph - 8.3
Alk - 8.3
Cal - 440
mag - 1535 (seems high)

all other corals are open and looking normal but I did lose a different acan frag about a week ago that was on the complete opposite of the tank

I would make sure the cleaner shrimp is not harassing the acans as well. They are notorious for stealing food from the polyps causing tears which can lead to infection. The cleaner shrimp could also be messing with them after the lights go out. Had similar issues with cleaner/peppermint shrimp.

good to know, thank you. I will keep a closer eye on that

At this point I'd still recommend dipping that coral in seachem reef dip.

So the only dip I have on hand is the Brightwell KoralMD Pro Coral Dip which I believe does not contain Iodine. Should I give that a try? and should I try and frag off the bad area? Now that I am keeping a close eye on it I kinda think its moving pretty fast through the colony

Looks kind of like brown jelly disease

I would only use an iodine based dip now since it can help with infection and is not nearly as harsh on the coral.

If it is brown jelly disease, which it sounds like fragging the best parts and throwing out the rest might be best if im being honest, as i had it and it destroyed all my lps

I've used peroxide and it works better than iodine for me. I've also been experimenting with antibiotics and have had a extremely great success rate. My lfs gives me their sick corals and I've used enthromyicin, chloramphenicol (works the best but hard to get), and doxycycline. This will usually stop the infection and prevent it from coming back where iodine dips have yielded poor results for me in the past. Definently brown jelly which is a bacteria/protozoan

How would I go about treating with peroxide? Is that is a dip or broadcast to tank? I would assume dip style but if you could provide more detail on how to go about doing that I would be interested in giving it a try. Was just getting some fragging tools together as I might do that shortly.

I use a 50/50 solution for 1 minute and treat as necessary. Peroxide is hard on corals but is more aggressive with Brown jelly. Sps do not do well with peroxide

do you think I should frag off bad area and then do the dip or just dip the whole colony as is?

And do you use standard hydrogen peroxide? 3%
