Toadstool behaving weired

[ElCommodore]

Added a toadstool coral to my tank over a week ago, since then it shrunk, does not extend much and I’m not sure but I think some parts have been dying.
Water parameters are:
pH 8,2
KH 8
Nh3/nh4 0
No3 15
No2 0,2
I would like to know if I should worry and take action or just wait.
I wanted to add a picture of the affected part but I don’t know how to add one. Maybe someone can tell me how to upload one because I think it would help

Look up toadstool shedding and see if that is what it is doing. How old is your tank?

I don’t know if you can see it clearly but it looks like a part is missing in the front

 

[Smirkish]

Oh wow, yeah I see it. Do you have any other coral? Any others acting off?

I wanna say it looks like a nudibranch has been eating it.

 

[Smirkish]

If it is a nudibranch it will likely come out after your lights are off. I found one in my tank not long ago, and it was clearly eating because it grew fast. There are a few species I believe that feed on leather corals.

Check this thread.

Just looks like part of it doesn’t want to open. I’ve had that happen. Check for nudibranches, but I think it’s just upset.

Agree with above, and worth noting that they do sometimes sulk. It could be just be shedding, but if the missing part is new I would keep a close eye on it.

 

[ElCommodore]

Yes the part not opening is new and thanks for the information. Besides the toadstool I have gsp and discosoma, they are doing well

 

[ElCommodore]

So far the part that is „injured“ did not get worse, nor did it resolve. Some parts fully extend others don’t. It’s is not as large as it one was. And I did not observe any nudibranches

Just give it a little more flow or baste it a few times a week to help shedding. Its fairly normal. Mine is growing directly infront of the return outlet so its getting blasted and growing like a weed.
