I found some nice flat pieces of slate at the beach today. Anybody have these? What dimentions would be Ideal? I was going with something like 2'' wide 2'' high and 6'' deep with a closed back. Any thoughts? I have Albino Bristlenose 2 females and one male in my 55, and they have not bred, but I haven't really tried either, I have read that it is easy to do.
