heat tolerant shrimps

[revolutionhope]

Greetings good folk of SKF,

I'm interested to know what people's experiences are with keeping shrimps at higher than normal temperatures?

My cherry cull tank had to endure temperatures between 28-35 for several days in a row this summer. All remaining berries were dropped at this time but some of them seem to be in good health still, while others have perished. There are a few batches of juvies in there at the moment and as they mature I am just curious whether the survivors were to breed again and then later generations were forced to survive the summer again and the process repeats over the course of a few years etc etc then to what degree might it be possible to breed a cherry shrimp at is "built for aussie conditions"?

Keeping shrimp cool can be an expensive and/or hobby-killing exercise and in my opinion it would be a great thing for them to comfortably survive temps in the low 30s (or higher).

I also know that the person i got my CRS from have told me that they had handled 28C safely at least for short periods. The ones that I got from him coped with several afternoons that reached 27 even briefly reaching 28 - and breeding didn't seem to be effected at all. Could anyone guess how much further the envelope may be pushed?

love n peace

When I kept RCS I had them in a tank around 28, constantly berried. CRS i keep mine at around 26.

From my experience and speaking to experience shrimp keepers, shrimp can adapt to most situations whether it be high ph to high temperatures. That said consistency of parameters is key.

most natives will take temps around 30 cherry up to 30 occasionally bees don't like it above 28

I have a thriving Cherry population that live in  a small pond outside under a pergola. They rarely get fed, they only get water top ups from my inside tanks, they do have lots of floating plants but no  filter. The water is crystal clear, there are always babies and they seem to be doing well even in our hot summers and cold winters. as mentioned stability is the key for them. The bee shrimp can tolerate high temps for short periods but they are much less likely to thrive. I have found a few in the pond that have been accidently thrown out with the water when they were tiny but I doubt they would survive long term.The other thing to consider when trying different temperatures etc is are they merely surviving or thriving- breeding and living the normal lifespan. It has been mentioned that higher temperatures are tolerated but shortens the lifespan of all the fancy shrimp. I do believe we tend to treat our shrimp as if they are very sensitive and they can withstand much harsher treatment but they deserve to lead a healthy comfortable life and not be stressed by conditions too far from their normal requirements.

thanks for all the input people, and if anyone else can add their experience please do :-)

I've just upped the temps in my tank with natives to 28 and so far no issues.
