I'm wondering whether I should be feeding my Lepomis megalotis (longear sunfish) throughout the (Utah) winter in my small pond. Temperatures are regularly but not always below freezing. I've read on other forums that you shouldn't feed goldfish and koi below around 50 degrees (F) because they don't digest the food. Is that specific to carp, or does it generally apply to most cold water fish? I'm struggling to find info about this anywhere else. Thanks in advance!
