I don't bite, all that often...
With all due respect truck, I'd have personally said the "expert" you quote is missguided or poorly researched realy... You can easily get an 8 degree swing in the wild habitat of fish quite easily, and hence pretty much anywhere between 22 and 28c is fine for most trops, with 26 being good for all but a few exceptions, most notably discus that want 28+ centigrade... Neons don't want it cooler, they come from the same area as Discus, so prefur it mid-to-high range for temp Discus are in pools rather than the main river though, so neons will melt at above 28, but cooler they perhapse aren't. Geo's round here do fine in pH 7.5 GH 8 and IME rams far better for me cooler... If you start digging arround, you'll probibly find most ram keepers do have things mid-range for temp usualy
