My pond at the new house is probably 500-600 gal. 30 small koi and one big one...we'll now 29 small koi. Denver area had major hail and lightning storms all afternoon yesterday and this morning my pond is over flowing a little, there's ice built up at the base of the waterfall and all the fish are gathered there as if they're trying to get more air? Did it just get too cold from all the hail? I threw my little airator into the pond near them to give them a little extra air. I'm afraid to feed them if the water is too cold and mimics winter. The hail got one fish...some of it was quarter size. Do I just let the fish do their thing? Do their bodies know what to do? I assume they've survived these crazy Denver temp changes before. Not sure what to do.
