Hi I have just put in a yellow light above my koi pond. When I put the light on the fish are jumping up towards the light. Is this a bad thing? Is the light stressing them out?
Hi tonight was the first time I put the light on. I had it on for about half an hour I got worried so I turned it off. I did not want to stress them.@Reshika
Maybe they are jumping for joy
No seriously I don't know but maybe they are trying to catch night bugs?
We need more info on if they do it every time or do they calm down after awhile. Try letting them get used to it and I would not leave it on all night. Fish need sleep also.
Do they do it every time you turn the light on at night? Do they actually look like they could jump out of the pond? If so that's not a good thing so turn the thing off.
Yes i think I will try leaving it on a few minutes a night and see how it goes. No I won't leave on whole night! ThanksI would try leaving it on for a few minutes each night till they get used to it and see how it goes. I think they will get used to it eventually and you won't have it on all night right? Maybe they think it's the moon and they are more active in looking for food then: http://www.fullmoon.info/en/blog/full-moon-fishing.html
Here is one that is not very scientific-Meyer,
Did someone do an experiment to try and prove fish react to colors? If so, do you know what the experiment was?
Too funny...Here is one that is not very scientific-
and one that is (sorry no link)-
Effects of background color on growth performances and physiological responses of scaled carp (Cyprinus carpio L.) reared in a closed circulated system

Thanks so much for everyone's feed back. I've been putting the light on every night. The fish seem to be fine with it now.I have yellow lights by my ponds and the fish do not seem bothered by the lights. It just could be that bugs are gathering around your lights and then the fish may be jumping to eat them?
Take a look at last night...
