I was wondering what temp. every one keeps their different species at. I mainly have central/south american fish and keep my tanks at about 80 F except for my bass and pacus out side is seasonal. In the summer it is about 85 and they seem very happy at that temp. In the winter I let it drop to about 77-78 F. I have read for years and been told that a good temp is 76-78 F but in the wild the water rarely reaches those temps. 1 fishstore in my area has signs posted around their fish supplies that state about 84 F is the correct temp. for healthy fish. I know the higher the temp the hungrier the fish will be and the more maintenance you will have to do. I don't want to know about that, I want to know about health of the fish.
....All my tanks, excluding the feeder quarantines, are set at 82 degrees...I believe the high temperature speeds up the metabolism and actual growth....
