how cold should the water be for CRS

Hi, how cold should the water be for CRS? For tanks using chillers. What will be a ideal temperature to set?

[imi_sky]

Well, i'm no expert on CRS's, but this is from what i've read, CRS are kept best at tempuratures between 25-28(degrees celcious)...but most breeders would say its best to keep it at 25°C.

I think it is better to keep the temperature below 26°C. lol

28°C is a bit too warm, I would recommend 25°C. :)

Using a AC fan to blow 2ft tank.. to 25 to 26...

But do be careful about it. CRS are rather sensitive and using a fan, the temperature might still flactuate together with the weather, especially over here in the tropical area. :)

I keep them sometimes at 21°C and they still have eggs.

Hello Armin,

I have also about 20°C in winter, but the people from tropical countries have problems with the heat, so they must use chillers and we need heater.
They only make the water as cool as necessary to have offspring and keep the shrimps healthy.

im jusing 17c in my shrimp tank is that to cold?

[Frank]

I don´t know how cold for CRS. Maybe 15°C limit for a few weeks?
As far as i know tiger shrimps have coldest temp. in winter about 5-10°C in nature.
Norway CRS are a little bit rougher of course? :joking:

At these temperatures (17 C) they stopping with reproduction. But if you raise after a time the temperature you will see many CRs with eggs.

Greetings Armin
