so i got an idea... i think this may work and really want input. so my idea is to through generations of breeding to slowly change warm water fish to cold water fish, sense most hardy tropical fish can survive in 55degree water im thinking that is i slowly breed cichlids in normal temps and each generation dropping the temp a deggree or so and see if i can create normal active healthy fish that will thrive in 55 or coller temps? now i think this may work bc with other hardy fish like puffers,molles, guppies that are found in brackish or even marine conditions and are taken out of those conditions and tank breed in freshwater for the most part do fine. and the same thing happens with most other tank fish when kept in a aquarium by a beguinner normally the gh and ph conditions are farr away from there wild conditions so sense i see that fish can addapt very well to water chemistry maybe they can addapt to water temp aswell? any ideas?
permenatly change temp conditions

Actually puffer are very sensitive fish, and marine / brackish species only head to fresh for breeding and thats only if they need to before venturing back to the ocean...
But your idea sounds like it may work... Although not sure how well...

I've seen tropicals survive in 55F but, not thrive. Trops aren't forced to live at such low temps on a permanent basis. When you lower temps for long periods of time, the fish suffer physiologically by a weakening or arrest of hormone and enzyme production. Osmotic regulatory properties alter to irregular levels. And, keep in mind that forcing adult fish to live in unaccustomed temps is by no means a gauge to employ when dealing with egg production, fecundity, development, and hatching. Quite a large number of developmental changes in eggs and embryos are temperature dependent.
The proposal has merit but warrants a thorough understanding of fish physiology and embryology in order to direct the experiments to successful conclusions instead of hoping for an accidental breakthrough. Good luck.

I think it would take hundreds of years to finally get a fish that could survive in the lower temperature.
lol thanks for the partial support, i kno that the colder temps effect there digestion, immune system, hormone, and enzyme prouction but i was hoping maybe if it was a very slow process it would help but i honestly unfortionaty know nothing about fish physiology. i just was thinking about it and thought that i ma be an idea but not one im eqqupt or able to try i just wanted to inspire someone hopifully
I seriously doubt you could ever achieve the results you desire. The metabolism of a fish will slow down with the cooler temperatures. Spawning activity in most fish is dependent upon temperature. Sorry, but that is just a dumb idea.
No more heaters? That would be a plus. J/k. Honestly though, i think we, as a species, create all sorts of problems for ourselves by attempting to alter the natural order of things to suit our own fickle needs. Get a Coldwater species.
