Ira Posted October 11, 2006 Report Share Posted October 11, 2006 I did a water change yesterday and just tested the salinity today and it was 1.023. My cleaner shrimp last I saw it was just laying on its side(Still aliveish) and then my basslet dragged it into the rocks. I'd imagine it's the drop from my normal 1.026 to 1.023 that caused the problem. I can't figure out how the salinity got that low though. I tested the salinity the day before and it was 1.026. I tested the salinity of the water change water and it was 1.026. Both at about the same temp, both gave the refractometer a minute for the temps to adjust. Poor little cleaner...

trinity Posted October 11, 2006 Report Share Posted October 11, 2006 I have had my Salinity as low as 1.020 and never bothered my cleaners, sounds like someone may have decided they wanted shrimp for dinner :evil: Quote Link to comment Share on other sites More sharing options...
Ira Posted October 11, 2006 Author Report Share Posted October 11, 2006 But was that dropping the whole way over about an hour? I'm just slowly adding salt straight to the sump to bring the salinity back up. Quote Link to comment Share on other sites More sharing options...
Ira Posted October 11, 2006 Author Report Share Posted October 11, 2006 And now that I've thought about it...It didn't take nearly as much salt as usual to get my water change bucket up to the "right" salinity. Quote Link to comment Share on other sites More sharing options...
trinity Posted October 11, 2006 Report Share Posted October 11, 2006 I did raise it rather quickly by 4 points and both my shrimps didnt mind, I have also gone from very high 1.030 to 1.026. Both these changes have happened with a 50% water change and nothing seemed to mind Quote Link to comment Share on other sites More sharing options...
Duke Posted October 11, 2006 Report Share Posted October 11, 2006 I would not expect the change in salt levels to cause this problem. 1.023 - 1.025 is not much of a swing really. Might be old age, how long have you had it? How long do they live? Quote Link to comment Share on other sites More sharing options...

Feelers Posted October 11, 2006 Report Share Posted October 11, 2006 I was under the impression that osmotic shock and temperature changes over a short period were really bad for crusteaceans in particular. Quote Link to comment Share on other sites More sharing options...
Pies Posted October 11, 2006 Report Share Posted October 11, 2006 Duke - I am with Feelers on this one, i've read in a dozen or places that small shifts in salinity can kill crustations. Quote Link to comment Share on other sites More sharing options...
Fay Posted October 11, 2006 Report Share Posted October 11, 2006 Just having breakfast and Frog said that the Saddle back clown was after the native glass shrimp I have in the cube by the time I looked the saddle back had caught it and taken it to it's Anemone. Hope it doesn't do it to the two Cleaner Shrimp I have in there Quote Link to comment Share on other sites More sharing options...
Feelers Posted October 11, 2006 Report Share Posted October 11, 2006 The red/white stripes of the cleaners is genetically programmed into most fish as useful, I'd say they'd stand a much better chance of not being abducted by the clown.
