What do you guys keep yours at? I decided to lower my temp slightly to 75F instead of the usual 77F. I get so much conflicting information on the web..and its not that mine appeared sick or distressed at 77...they were fine. I just wanted to try this since it seems theire native waters in China are cooler + some people say they will more readily breed at lower temps (I've finally noticed at least 3 berried females after about 2 months). Is it true their colors come out more pronounced at lower temperatures also?
