Hello Gianne00
Welcome to forum, – as this is your first post, it had to be approved by an admin,- this is now done 🙂
Regarding your questions, – I will leave that more to others who are experienced with rain water, I am personally not that.
But I can say that I keep my paros at room temperature, and although a bit higher perhaps, 22-23, I dont think temperatures in that range is a problem for spawning with paros. Even in those places in nature where the temperature is high, in the lower regions of the water the temperature may be cooler than that, and paros are not excatly living in the surface of the water where the temperature is higher.
