Shrimp Temperature Tolerance

Recommended Posts

kapp

Hi All,

I've just set up my first shrimp tank with the shrimp, CRS and some chameleons, to arrive this week. I set up the tank in my basement spare room which has a very constant temperature. The room always feels pretty cool but since I've had my control unit hooked up the temperature of the water has been 26 degrees. I put in an old-school thermometer and it confirmed the reading. I turned down the water heater in case it was off but nothing. I even turned off the heater all together. The water is staying between 26.0-26.4 degrees. I've now put a desk fan on top of it to slightly cool the surface of the water.

So my questions are simple, is this too high for CRS to either live and / or breed? I was thinking of getting some yellow cherries as well, how would they go at this temperature?

Thanks.

Some will say those temps are border line for CRS, The chameleons & cherries will do fine at these temps.

Cherries would flourish in those temperature, but CRS's would prefer temps at 22-24. There are other factors though, if your water quality and other water parameters are perfect, they CRS, may survive and breed.. Just off experience, my son's tank is a 20lt, but with a eheim 2211, and great WP....temp is between 25-29 degrees, and the CRS/CBS has been breeding. Shrimplet survival isn't great, and their colouration pretty ordinary, but possible though...

Honestly, if you're not considering a chiller, and those overhead fans won't bring the tank temp down under 24, then I'd advise to just keep cherries...so many colour variations now.

Thanks BB and al4n. JonX has told me good oxygenation helps CRS handle higher temperatures as well. I'll see how the fan goes. It's only a 2 ft tank that I've split into thirds, so I guess a small chiller wouldn't be too expensive (???) if I have to go down that route.

I've had chameleons, some CRS and yellows in my planted apisto tank that sits at 26 degrees. So am guessing they can survive but wasn't sure about the breeding or long term survival.

Agree with bb. 26 is borderline. Reduces their lifespan but they will grow quicker as well. Almost too fast for their health. High temperature also creates way too much bacteria which the crs might not be able to handle at times

Wow - these guys are even more complex than apistos...

Its entering the cold season now. You will be sweet -

Might want to get a chiller next summer.

thats weird because my tank in my room fluctuates from 24 - about 26.5 and the crs have bred really well for me in that tank. got a nice colony going. but the yellow cherries in the tank wont breed at all for me at all... in my outside tank however the temp is like 21.5 - 22 and the cherries have gone wild

There's other water parameters as well. KH, GH, TDS ..etc would effect their breeding pattern.

Thanks BB. Yeah from the small amount of research I've done so far, the parameters for these shrimp, other than temp, seem very similar to apisto's, ie. Ph6.2'ish, soft water. Am hoping my experience with apisto's will give me a leg up here.

      Mine is a DIY Chiller, as you know a peltier has a hot side and cold side, for the cold side to stay cold, the hot side must be kept cold and with a heatsink and fan to cool it down. My DIY chiller has two sides and two water block. blue aluminum block with tube leading to the outlet of the canister filter and back to the tank to chill the tank water. copper block is to cool the hot side of the peltier, with copper block to the radiator/fan and a water pump looping. The problem is the tube from the water pump came off, apparently the plastic from the pump started to melt and the tube came off and the looping side had no water, so the copper water block stayed hot all the time with heat transferred to the cold side of the peltier also heating the water. since the copper takes time to cool down, most of the heat and the room hot temp had already heat the tank water to about 45 C.

      Try testing it again and see what you get or to confirm that the previous were right, especially the higher Ph reading is all I can recommend! If there is some explanation for the difference hopefully someone will reply and let you know, but I expect there won't actually be a difference if you do it again? Simon

      No that's not normal. But I don't know which tube in your loop had come off. Can you show us?   Yes that would have helped a bit, and at least give KMS more time to have found the issue by turning off the chiller. As I understand, kms has a peltier style chiller, and a tube of the pump had come off, which meant that hot water from the hot side of the peltier flowed back into the tank. So if the chiller was on the same temp controller, it would have turned off the chiller at around 26degC. The tank might have got warmer in his room, but it would have been at a much slower rate, and certainly would not have reached 45degC.

      I'm using the API master test kit with the dropper bottles. I was just very confused at how much more akaline the water was coming out of the filter compared to the water out in the open. I can't imagine how this fluctuating change in pH is going to be beneficial for my crs.

      What type of test are you doing strip or drip? I use drip tests and always ignore the first attempt as no matter how well I clean and keep the test set it is often way out of line. Las time first test was Ph8, second test Ph6. Sometimes first attempt looks ok so I have no idea what is going on????? If you just tried once it may be worth testing again? Simon
