In summer, I have measured the temp in my bowls to fluctuate from night time 22 to 32 C when the sun hits. If not because the room is AC, I am afraid there could be a crash if the temp climbs above 35C. PH fluctuation is also substantially, from 7.4 to 8.5 at the peak of direct sunlight and photosynthesis. My cherry shrimp survive but don’t multiply which can be caused by too small water volume (< 3 liter), lack of WC, food or other factors I don’t know.
