I recently picked up a 20L that will be plumbed into my system as a display fuge. I'm looking for ideas/pictures of what/how to stock it. I "plan" on stocking lots of macros.. lighting isn't a problem, so I'm pretty open there... Just looking for ideas as to what you all have stocked in a display fuge, and some comments on substrate (without getting into the miracle mud debate if possible, as I think I've decided its not a direction I'd like to go), and the "best" macro's that won't lead to problems in the DT (going sexual/spores)
