Water Gardening: Are koi nocturnal?, 0 by art_n_garden

I ask because well, long story short- I put my pond in late in the season (beg. of sept) and got a few small koi and goldfish to start with and because it was so late, I never made friends with them (they were barely eating at that point). I never ever saw them during the day. They thoroughly hid themselves under my filter and in folds of the liner. I have very secretly staked them out for hours, and saw them dart out for food only a couple times when it was warmer. ;)

But every night, even now when the water temps are in the low 40's, high 30's, when I go out at night with a flashlight, I see the koi and goldfish out roaming about through the lily pots and rocks. Never ever have I seen them do this during the day since I got them (even though I know they should). Eh? I'm very interested. Susanne
