Hammer Coral Mouth Opening?

[alexiosue]

I recently noticed my hammer corals mouth keeps coming out (if that is in fact his mouth). Usually it just happens for a couple of minutes then it’s covered up again. However I am worried that something is wrong. I just got the coral roughly 5 days ago. Checked salinity and all other levels and everything seems to be fine. I also noticed the hammer coral behind it seems to be tilting in the other hammers direction. I don’t know if this is because of too high flow but the fan is not pointed close at all. I also noticed it has sucked in its tips in order to get more light on lower ones and was wondering if it’s normal for hammers to do that? Please let me know asap!

“Seem fine” are not parameters. People could help if they had numbers. Also how old is the system?

no, thats not normal, I've never seen my hammer do that.
Share some more info on your tank for more help, ie., tank age, lighting, flow, parameters, how are other corals doing, etc...
