Honestly I haven't worried about the temperature at all. I know guppies need a more warmer climate then goldfish do but I've always kept it the same around 22c (around 71) and they have been fine I used to have a heater but it broke about 8 months ago and everything seems to live on peacefully. As for the photos, I reckon I take around 80 and get 4 good ones Max .It's about patience haha sorry I can't be more helpfulMy garage temps are at 80 degrees already. I have two 10 gal tanks with fry. I need to find away to keep the temperature below 86 degrees. Advice?
