Whats sad is that you really believe you're right.

Thank you!

I appreciate everyone’s help and if he’s receding or not, I’m sure he’d appreciate a meal. If nothing else the others in the tank will. I still have a ton to learn
 
They are all over my tank, especially on the back wall. I remember asking the LFS about them back in the day, was told they are harmless and I immediately stopped worrying, forgot what they are called. My urchin will eat some and they seem to only like shady places.

Spirorbid worms. My sump is covered!
 
Here, let me help turn around the mood a little;

I hate to admit this and will probably pay for it in ways I cannot yet imagine BUT...



I kind of miss that @JoshH punk coming around... ;)
 
Question. Does the calibration fluid expire? Mine doesn’t have a date on it. I got it from BRS I’d say about a year ago, perhaps little longer.

You’re always upbeat Crusso.

Not until a very long time but you will notice some precipitation before then rendering the calibration fluid unusable. (Unless you’re realllllly good about keeping the cap closed immediately.)
 
The hammer discussion... I would first say alk. Euphyllia hate low alk, high alk, any change in alk... moody corals. Anyway, LT and Seabass are right. Young fast growing euphyllia have a lot of tissue covering the skeleton down the stalk. On older colonies this tissue doesn't extend down near as far and baby heads will pop up where the tissue used to be.

I will say this coral is stressed and most likely due to low alk or an alk swing. Leave it be and stay on top of water tests and changes and it should recover. I've never seen a frogspawn of mine eat anything FWIW.
 
@sebaseau The PH in her tank would have to be seriously low for anything to mess with the skeleton. The hammer can die, the polyps can bail out, and the skeleton will still be there. The arrows you very meticulously added are pointing at skeletal growth, not recession. As she has just done a water change, I think that’s the likely cause. (A parameter shift). Occam’s razor...the simplest solution is most often correct.
