Mine are doing fine in my 32 celcius water. This is based on those themometers that you stick to the outside of the tank. Not sure how accurate they are, but I figure they can only be 1 or 2 degrees off.

For my case, whenever the water temperatures goes beyond 30 deg, they starts jumping out of the tank.
I have ghost and malayan shrimps...

Same here, in my 2ft, if forget to turn my fan on, I'll find "hei-bee" on the floor. Yamatoes will look like they just came out from the steam boat.
Interesting. I've never had mass shrimp death from my tanks due to temperature and usually I introduce them to the tank after the usual "float the bag for 15 mins" acclimatisation. If they can survive handling and a change in temperature from a LFS tank to a home tank, why can't they survive a slow change in an established tank that didn't get fan cooling for a day.
Unless my thermometer is really crappy. Other possibilty is that because LFS do not chill their water, and thus the shrimps are already acclimatised to warm water.

This only happens to my 2ft, has never happened to my 3ft even though I have forgetten to turn the fans on sevral times (but now setup to turn on with the lights). I guess the size of the tank plays a part too.
I know this is an old thread, but I can't find info elsewhere so here goes my question. I have been keeping bee shrimps (black) and I notice some of them had turn slightly red (and still alive) and eventually died. I measured my tank's temperature and saw it was 30.5 degrees celsius. I guess it was too hot for the shrimps thats why they turn red amd eventually die? I am suspecting my lamp is too close to the water, but most lfs has the same height as mine.

Another question I have is, is it normal for shrimps to always vibrate their gills so rapidly that it seems like they just finish a 2.4 km run?

Shrimps have gills???
I'm back & keeping 'em fingers wet,

Hi Ronnie,
I am unable to show you due to my poor camera's quality, but here is one similar video that is like what I see in my shrimps :
https://www.youtube.com/watch?v=lZQxQ5UGtBQ
I haven't observed my shrimps at such close-up detail that i could see their internal gill parts moving within their shells (will need a very good macro lens as they are much smaller than market prawns)... but low oxygen levels in a tank definitely affect them greatly. Usually if there is lack of oxygen, they will either become sluggish or start crowding near the water surface.
Warmer water holds less oxygen so if you observe your shrimps "breathing" rapidly, it would be an indication to improve oxygenation (ie. create more surface agitation from filter outflow, run an air stone etc), or find ways to reduce the tank temperature.
Maybe FreemanAng is referrring to the part behind the legs? I saw my shrimps (the bigger ones) sometimes "flip-flap" the "vents" at the part before the tail. i was quite fascinated by that action.
I think FreemanAng is talking about the mouth. There's a tongue like thingy that vibrates which I believe it's the lower jaw or something.
shrimps do have gills.
