Frogspawn and torch disintegration

[jpontier212]

I have a frogspawn in my tank for about 3 months and just recently got a torch coral last week. I dipped it prior to putting it in my DP with Bayer. Today i noticed that my torch was fully retracted and my frogspawn 's skeleton looks partially eaten. I don't know if something is physically eating it or if it's some kind of reaction. I recently had a major nitrate spike due to over feeding. Thanks to my family[emoji2] [emoji26]. But i did a 30g water change on my 75g tank. I have 2 misbar clowns, flame angel, Kole tang, mag fox face, and a starry blenny. The frogspawn and torch are on the substrate. I have diy lighting system, blue and white leds. They are in mid water flow.
Present paramaters
Ammonia 0
Nitrites 0
Nitrates 10ppm
Cal 400
Phos 0.25
Alk 8 dkh
Mg 1300
Ph 8.1

Any help will be greatly appreciated

30 gallon water change on a 75 gallon take ( maybe 60-65 with water displacement?) is roughly 50% water change. That may have caused a shock of some sort.

IME, euphyllias really don't like salinity or alkalinity fluctuations, dirty water is somewhat tolerable for them.

Also, how close are the torch and the frogspawn? They may need to be separated several inches to keep from warring with each other. I have a large frogspawn which fell over on top of a torch frag one time. The torch lost. I kept the skeleton around for a long time hoping there was enough left that it would eventually come back. It never did.

I would agree but the deterioration started before the water change. I got a leather coral, Kenya tree, candy cane zoas, blasto, acros, star polyps. Nothing else seems affected except for them 2. They are roughly 7-8 inches away from each other

They're pretty far from each other. Roughly about 8 inches away from each other

Then I would have to lean on maybe the bacteria infection theory. Brown jelly disease and many other issues euphyllia are succeptible to.

I've noticed that once the tissue starts receding and deterioration process starts to begin, it's a process that is really hard to reverse. Only success I've had saving any heads was when I'd chop off branching heads that weren't receding yet. Wall hammers are another story lol.

Another thing id like to note is the flow that they receive. They prefer low-to medium indirect RANDOM flow. I've seen such a huge difference in size with little flow tweaks like such.
