Rili Shrimp in unstable temp
I have a "sort of"-walstad tank set up with rili shrimp and two amanos. It has no heater and the room is nomally around 22-24 degress in daytime, sinking to 19-20 during the night.
The tank on the other hand is up to 30 C when the sun is on it, which is between 10am - 3pm. I've red that people have kept breeding rili in 30C with no problems, but during the night the temp drops to around 24-25C. Seeing how temp rises and drops like this outdoors as well I figure its not a big deal.. or is it?
