14k vs 20k
I run 20k 25oW MH and the other day one of them burnt out. I had a 14k bulb handy so I replaced it for the meantime and noticed they fish really like the 14k side a lot more. All of them would congregate to the 14k side and just swim in circles there.
I never gave any thought to what fish prefer until I noticed this. Anyone else experience this?
