I saw a Filipe Oliveira video where he was running an aquarium without any heater, with a pair of honey gourami (Trichogaster chuna) as the centrepiece. It got me thinking about which other species are happy in the high teens/low twenties, outside the usual suspects (White Clouds, Paradise fish, Variatus platy etc etc). The lack of equipment and spend on electricity appeals to me, though I do appreciate the advice suggesting having a heater set low just in case.
I snorkelled with a bunch of Devario regina in supisingly cool water in Thailand last year, I suspect various other
Danios and Devarios would be suitable. I actually had a heater failure last Christmas, with my Emperor tetras living (and breeding) without for a couple of weeks while I was away, to no visible ill effects.
Anyone else had success with other species at this kind of range?
