Hi,- I am doing a little bit like Peter is doing, – I am using one of each. The warm led strip is too yellow, – I had bought this first, but didnt like the light, – and I also think the plants did less good with this one.
So I added strips with the clearer light, and I find that the fish dont bother. I have a few tanks, where the male is having his nest just under the surface, and in order to make the light a little less there, I make a ‘shadow’ (piece of black paper, or anything really) at the glass, and then raise the strips a bit above this.
The strips should have a self-gluing side on one side. I have then glued them to a narrow piece of hard wood, – and then raised it up a little, so the strips dont lie directly on the glass. This works fine.
I use it on my big rack, this one
