acclimation for crustaceans

[Delphinus]

Hermits I wouldn't worry about so much. A lot of them are found in intertidal areas, tidal pools, river estuaries, so one could speculate that they are perhaps adapted to varying salinities/temperatures/etc. Just speculation though. If it's a species collected from deeper water this may not hold true.

That said, I think it's "nicer" to them to acclimate rather than throw them straight in. If that helps you any...
