Everything but toadstool is doing well

[DracoKat]

I've had my toadstool for about 5 months. it's one of the first pieces I put in my tank. It was growing and doing well.

Then I noticed for the past few weeks it's shrunk and its polyps aren't coming out anymore. I thought maybe the rock shelves I've added was shading it, so I moved it to the other side of the tank in the light, on the sand bed (it was on sand bed previously). It hasn't bounced back.

my goni is wimpy- but looks OK.

my other corals are doing really well. Acros, Zoas, duncans, long tenticle plate.

Can someone help me figure out what's going on?

I'm going to bet if all is doing good, its normal. They go through spells of molting and growing.

I had one go completely white for a year then came back and it was fine

wow, really fast responses, thank you!

So you think it's just molting?

If they are molting they will be bumpy and shiny.

can't tell if it's shiny, but it is bumpy like the photo.

approx how long does it take for it to molt and extend again?

A month. They go through spirts to where they do it off and on for a while.

Leathers do strange things just leave it alone and see what happens
