Question on shellies.

[efors]

Sorry my friend, but I really don't know who the N. boulengeri is.

Now I got it!!! The confusion is that it is not Neolamprologus, but Lepidiolamprologus boulengeri. We talked briefly about them in my fish club meeting today.
And yeah, I also think that the rock pile in the center may work; as Pitt and JPappy stated.
