Shrimp temperatures

[a1matt]

I want to get some Amano shrimp and\or Cherrry shrimp to eat the hair algae in my tank.

My main question is what is the temperature ranges that I can successfully keep them in? More specifically, will they die from overheating if I put them in my tank!

I normally have my heater set to 26deg.C
I say normally because for the last fortnight we have had glorious weather in England, and as a result I have unplugged the heater.

So my tank now varies from about 22deg.C up to 28deg.C
Most of the time it is around 23-5deg.

If this is too high a temperature, then I guess I would need to invest in a cooler to maintain an exact temperature (or wait until Autumn before buying shrimp ), how much would one of these cost? where would I get one? Do I have any other options? (my tank water column is apprx 160l\42US gallons).

Re: Shrimp temperatures

I keep cherry shrimp at a little bit higher temperatures than 28 C. So far no problems. My low temperature during the winter is around 22 C - again no problems. Cherries are very rugged adaptable shrimp from what I see.

Re: Shrimp temperatures

That's good to hear - thanks.
I just hope my angelfish doesn't find them a good size for eating!

Re: Shrimp temperatures

It's 42C here, the cherries still live as dohe Amano's.
BTW, so do the plants.

Tank is about 35-38C.

Davis is 108F today.

Re: Shrimp temperatures

By English standards, that's very hot weather!

I am now confident to buy my Cherries and Amano's

Thanks

Re: Shrimp temperatures

South of here about 4 hour drive is the Mojave desert and then Death Valley, 130F is a common summer temp there most every year. Desert pup fish live in that region. I'm amazed that plants can live in salty, sorching heat without hardly any water.

But there they are.............

I've found Chara and Veronica growing at 46C in the Sonoran desert further south. Echinodorus berteroi at 42 C in Santa Barbara county. Hydrilla at least at 40C in Florida.

Plants generally do better at lower temps though.
Discus folks often maintain high temps also so they are not a bad resource for seeing what lives.

See what info that is out there that makes it and does well, not so much the failures.

All you need is a few folks that are doing it at say 35C to prove that 28C is not the main issue.

Re: Shrimp temperatures

My place probably gets to 30C and above during the daytime, and my shrimp are dying like crazy, as they did last summer. It seemed like quick change in temp this year, and maybe that did it. I sometimes consider a DIY cooler for a shrimp tank, fwiw.

Re: Shrimp temperatures

More circulation and water movement(also cools the water)_, and more CO2.

Re: Shrimp temperatures

If you use a light hood, and no cover glass, you can cool the water as much as 10F by installing a little fan in the hood, to blow on the water. The evaporation cools the water. I use a 40mm diameter, 12 VDC fan, with a variable voltage universal power supply to let me drop the speed of the fan a bit. The down side is that you have to be adding make up water quite often, to replace what evaporates.

Re: Shrimp temperatures

Fans are very popular in Singapore and many warmer locations.
Work well, but yep, they do require topping off of the tank almost daily at times.

Re: Shrimp temperatures

I like the fan idea as well and most appealing in my mind is a non-CO2 moss tank with plenty of sufrface agitation. However, with several tanks and encouraging evaporation, opening the door to my place starts feeling like stepping out of a plane into Singapore

I will try more current and increase CO2. Thank you.
