Caridina Shrimp with SA's heat.

Hi everyone. I'm new here. Apologies if this is the wrong place to post!

I wanted to hear if there are any of you who keep Caridina shrimp without a external chiller?
I set up a tank for them about 3 months ago and I've been cycling, no shrimp added yet, but the heat has been intense this summer and the tank water regularly hits 30C, and that's been stressing me out a bit. The tank is in my fishroom where I don't have an AC. Have any of you guys kept Caridina in the heat successfully?

 

if you dont mind the humidity and topping up your tank regularly, you get clip on fans, that blow across the top pf the water, and thy can reduce the temp by a few degrees:
