If you are not using a refractometer, you should be. If you are using a refractometer, when is the last time you calibrated it?

I lost an urchin because my refractometer hadn't been calibrated recently and I thought my SG was 1.026. When I calibrated the refractometer, the SG was 1.023.

1.020 if measured accurately is definitely low, you'll want to bump that up slowly a few points & ensure your measuring equipment is reasonably accurate.

My guess would be that the tank was medicated at one point.... Acclimation could be the problem but I've lways just temperature floated, then released my snails and crabs with no issues...... Hydrometers are almost always "out"..... You must keep them clean or salt build up may sque your readings.... Clean it thoroughly, then take it to your LFS and have them check it against a refactometer.....

You don't have one hermit crab that seems to always survive do you? I had a nasty hermit that would kill every other hermit or snail it could get at. I always found my hermits to be almost indestructable and to see your fish and snail doing fine in the pics I would suspect predatation if raising the salinity doesn't do the trick.
