It's currently 55f in my house, I have tropicals, sooooo....yes.
There is an article by Alf Stalsberg called Hispaniola Oh Island in the Sun, or Dominican Republic Oh Island....Cant remember for sure.duanes , Nandopsis haitiensus (Haitian cichlid?) is specifically high-temperature? Are they from specific sea-level ponds/rivers? I ask as I don't think there's a river on Jamaica that stays above 25C year 'round; they come out of the ground at 65F and don't get much chance to warm up unless there's a drought.
I also ask as I don't use a heater unless I really have to: IE ich infestation during a winter storm, though this might change for this year & new house. We also don't get much access to better, higher-dollar brands.
