Over the last couple of days my nem has been behaving strangely.  It has spent most of it's time with virtually no extension.  It looks all shrivelled up.  I spotted a couple of pieces of my porcelain crabs shed under the edge of it.  I've used a pipette to wash them out.  I wonder if that could have been irritating it?  It still seems to have a grip on the rock, so that's good.  I can see the mouth is wider than normal, but no sign of the inards.

Any thoughts?

Has anything changed recently? Have you recently done a water change? They convulse and shrink right down and back up to flush water out of themselves, and take in new. Most do it through the night, an "internal water change", but if it's been that way for a few days, it seems it doesn't want to take in the new water.

Any pictures?

As you know, keep your eye on it's mouth, the tightness of the mouth is a really good indicator of health.

It's foot is in a hole in the top of a rock, and in the centre of the tank, so it's a hard angle to get a shot of, and the lights are down to 1% blue now.  Will see what it looks like tomorrow and try to get a shot of it.

I went away for 4 days last week.  I fed the tank as normal before I left on Wed.  They went without on Thur, my dad fed them on Fri, they went without Sat, I fed them when I got back Sun evening.  All the fish and corals look fine.  It's just the nem.  I only target feed the nem every few days anyway, so not sure why it would react so much to that.  Not done any water changes (ever).

Hmm...

Lots of people report issues with their tanks after having even the best of trained "tank keepers".

Just check your parameters and keep your eye on the mouth.

If you've never done a water change, it could be a coincidence that some minerals the anemone needs have gotten to the point it's annoyed by them right now. I'm not saying it is, but I wouldn't rule it out.

It swelled up a little more today.  I managed to get a small piece of fish into it, so I'm hoping that gives it a boost.  Will keep an eye on it.

If it's sticky, that's an even better sign of health than the mouth tightness. The mouth tightness thing is just a visual thing. They lose stickiness before the mouth starts gaping, so if it's taking food, I don't think you've anything to worry about. Just whatever change in water chemistry has encouraged it to flush itself and take in new water.

It's had another day shrivelled up, then today it was looking better again.  It's not moved at all.  Very odd.

Since my last post it's remained shrivelled up.  I tried putting the porcelain crab in the sump, as I read that they can sometime irritate the nem.  it swelled up on one half of it after this, then shrivelled up again over night.  I tried raising the rock the nem was on to give it more light...no luck.


It had maybe three/four days semi-inflated over the last 20 days.  After close examination this evening, I believe the tentacles were rotting.  I gently pushed on the foot and it peeled away from the rock.  I have therefore removed it, as I'm pretty sure it was dead.

Cause they can sometimes have a go at nems, and they're worse than cleaners for trying to take food from nems, rougher too.
