Thanks for the input, wayne!

I agree that the idea of using conventional substrate in this kind of biotope is potentially problematic! I think that the "rubble bottom" is essentially a barebottom system with rubble rock serving (at least from an aesthetic standpoint) as a "substrate". This is why I belive that we are both experiencing some success, with careful and due attention to husbandry procedures.

I've been using the little flat pieces of broken slab rock to construct a "matrix" of sorts, which still leaves some open areas. Sounds similar to yours.

I'd love to see some pics, if you have any!

Thanks!

Scott
