Change fish to other tank in winter and summer

[Karalak42]

Hi guys

I wanted to ask ur opinion on the viability of a project I had in mind but not sure it would fully work
So the spring summer and begin au autumn fish would be in a big tank that would need little or no heating in a big interior pond and in the colder period move em in a smaller heated tank but 1 or 2 degrees lower and less feeding. Considering it would be fish that in summer would be at 24 or 25 degree Celsius or more and in winter at 23 or 22.

For a question of energy costs mostly. No specific species in mind
Free to some species suggestion (of bigger fish over 2 ft or more size preferably)

Ps I heard clown featherbacks could be a ok choice

Speaking from the perspective of someone who must supply heat for at least 8-9 months of the year, I can certainly understand the appeal of saving some money on electricity. Frankly, I can't think of a single species that would be happy at 25C and will suddenly keel over if maintained at 22C.

I have no specific suggestions because I have no idea what fish interest you. I think you should decide what you want to keep, then do some research on those particular species to determine the sort of temperatures to which they are best suited.

Yea beceause it would be moving from a 2000g to a 500g for winter for ex
