LED blindness

[Isaiah Shipp]

So I have a Marineland LED light on my 75 gallon and got my Flowerhorn a few weeks back and as the weeks went on, my fish started acting strange. I tested my waters and everything was fine, I've had many fish in this tank before and never had a problem before. Well I sold all my fish and got this LED Marineland right before my Flowerhorn. And the past few days I thought he was just being stubborn and not eating but I figured out he couldn't see the food! I grabbed some long Tongs and put the food near his mouth and touched him with it and he snatched it up for 5 minutes. I turned off the light for a full day and he is fine now. I had the lights on for about 12 hours a day so nothing excessive but they were blinding him. BEWARE! Anyone else heard or experienced something like this?

 

[ehh]

So he was able to see the food after you turned off the light?

No, so it took a few hours for his eyes to get better but a whole day for them to be completely better. My bare bottom tank May of enhanced the LED lights because of reflection.

I did hear something about blue LED's leading to retinal damage but I currently run a few LED's on a few of my fish tanks and haven't had any issue. I think the old school LED's were more damaging but I think they have improved

Nuts. First time I hear about this. I just looking into led lights too haha
