I have fake Lillie pads in my 260 cichla tank that look killer. I'll have to post a pic later but they look real, no maintenance and I've arranged them in a way that most of them are under water and as if growing up to the surface. I like it.
I'm enjoying the benefit of real plants as they add to filtration. I have kept anubis, crypts and java fern successfully with these fish. I don't know how edible Lily pads are for fish... I know turtles love them.
