Hammer coral died overnight

[hilltopper152]

Within 24 hours this hammer coral which has been in my possession for two years and 10 months in this tank is dead. One head (the smaller) is okay as of now it seems. I plan to check parameters tonight if I can but everything else like salinity and temp seem fine. Tank has two tangs, two wrasse and a clown. Mostly snails for CUC. Two leathers just came back after sulking for a week. No other obvious issues and in fact many corals improving in looks. Excluding a couple small sps frags I bought a month ago (trying some in this tank). I also dipped the corals that were newer.

Based on pictures is this brown jelly disease and is there something I should do now like pull the entire coral out? Not sure if it's bad luck, disease or something decided to bite it. Haven't seen a coral ever bit to this point. I believe this happened today during lights on work hours or late night before.

Thank you!

Unfortunately it seems it won't load. Says error with no explanation. I'll keep trying.

was the hammer too close to any other coral with stingers? Could be coral warfare when you’re not watching.

Can't get a photo to load to save my life ha. Closest coral is the yellow fiji that has been closed for a few days. It admittedly is back today so maybe true that the hammer which has been growing touched it but not sure if possible. Nothing else can reach it. A torch is below it but they are decently far apart.

Yeah of course. I have been probably the most dialed in I ever have been because currently trying to fight a corner of cynao, measure calcium consumption, and recently shifting some sps around. I haven't check parameters like alkalinity since two nights ago. I went two years with this coral with all kinds of mistakes and it lived in 4 nanos early on. This specific coral is my shocker but yes I'm not s biologist or excellent keeper. If I was I wouldn't be here ha. I'll send more info for you soon. Can't get this app to function properly unfortunately.

Looking like left side of the hammer still doing well and from the pic I see your other corals doing well. My guess is that figi leather coral did something. Apparently the figi leather can release a chemical called Allelopathy. It’s a toxic chemical they release to neighboring corals .

I would cut off dead heads and hope the remaining head survive . Maybe move to a diff spot?

Was actually looking for numbers and procedures...

I definitely lose corals every once in a while but this one has grown from nothing so you probably are right. I started using carbon a month ago knowing that my leathers were getting huge. But you are most likely right. I wondered if tang did it but that would be a first.

Salinity is 1.025, temp is 77.4 F, alkalinity 7.5, skimmer runs all the time, water change of 15-20 gallons weekly lately with every other week months before, 75 gallon with 25 gallon sump, nitrate 6, others need testing still. Thank you

What about no3/po4 and feeding schedule/ stocking list?
