These guys can make some fairly strange shapes. I am absolutely not an expert so don't stop paying close attention to it, but all of my hammers and torches and anenomes and bubble corals suck in, deflate, open up their mouth etc. from time to time. I know when I got my first hammer it would completely retract until it just looked horrible...then a day later it would be fully inflated and opened up.

I have also noticed that when I feed my bubble coral, for example, it will shrink up the next day. Sometimes it's completely shrunk in and just looks awful.

You'r salinity it a bit on the high side...so I'd work slowly to get that down. but otherwise nothing seems crazy. Could be the change in salt just ticked it off and it's gotta work through some issues.

okay yeah I have been Mag dosing for Byropsis....so it could be the reason.
Just been about 2 weeks now so starting to concern me....i think it may be splitting from the other mouth.......as 2 weeks ago there was barely a crack now there is almost a canyon between them...could this cause this abnormal/sluggish behaviour?
