I have been dealing with a nem that's not been looking the best. Bleached, lost of tenticles length and small. The mouth is not gaping.
Possible problems.
Nitrates are very high.
I was target feeding everyday.
@Katrina71 was extremely demanding I stop. Told me 6 times in the course of a couple of hours. Don't worry I have.
Also lighting has come to mind.
At night the nem expands 3 sizes bigger. Two days ago I found it on the sand. I moved it higher up in the tank and it quickly went to a less lighted are of the tank. It's position is in the middle of two large leathers and a colony of zoas.
I'm not touching it. It's also a lot bigger than it use to be in that spot. Still bleached but definitely more inflated.
Attached is pics of how it looks now
