I like the look a caves and ledges. With your substrate, they could probably hollow out their own little nooks and crannies next to various objects. I think 6-8 would be a good number of specimens for your tank, unless you really want more because you are especially fond of them.
I'm going to add a driftwood shelf soon, just need to time to set it up, been on my list for weeks now, as I want to plant it with java ferns first and I am sure that will provide enough additional hiding space... probably some crypts in front as well.
I like the idea of 10 as a minimum for any fish shoal and I have eight cats... I don't NEED more.
I thought that they would use the space under my larger driftwood piece but they don't. I think because it is open to the front. I hesitate to open it only to the back as I could not see into the space and would never know what might buildup in there.
