Snails not moving?!

[Kial]

So it seems all of my snails have stopped moving, however they are still attached to the rocks. It's been over a week now with no movement.

I'm guessing If they were dead, they would topple off into the sand right?

Trochus, turbos and nassarius.

High magnesium is supposed to paralyse them, however, I have no idea if that’s fact or myth, never having high magnesium myself.

If you check your magnesium let us know what it came to. If they begin moving again after reducing it, let us know please. I have seen snails recover from what we thought was magnesium poisoning. Magnesium can definitely paralyze snails, the debate is over how high the concentration has to be. When scientists use it to anesthetize they tend to use levels we do not see in aquariums, so there are gaps in knowledge that need to be filled in:

EVALUATION OF EUTHANASIA OF MOON JELLYFISH (AURELIA AURITA) USING SIMPLE SALT SOLUTIONS

Immersion euthanasia methods reported over the most recent decades for aquatic invertebrates use organic alcohols or halogenated hydrocarbons that can interfere with nuclear magnetic resonance (NMR) analysis. A rolling study design evaluated potassium chloride (KCl), magnesium chloride (MgCl2)...

I'll check my mag tomorrow. My last reading for mag was 1400 and I haven't been dosing it so can't imagine it would be high enough to paralyse them. Well I'm hoping not anyway

One way to test is if that is the issue is use freshly mixed salt with distilled water, and see if they come back to life.

Just checked my mag and it's 1440 which isn't too high.

I noticed when I put some pellets in, the nassarius came up from the sand very slow, but moving.
