I'm trying to decide what to do with my Baileyi Puffer tank to make it look less naff. At the moment he's in a Rio 180 with a Tetratec EX1200 that's not quite cutting it, so I might have to get some more powerheads in there for water movement. Anyway, I've tried wood, but all my pieces leech too many tanins, and I don't like the brown look for this type of scape. He's from a region with lots of rapids, and is an ambush predator that lies between the rocks waiting for something to swim by (or my fingers, evidently), yet the rocks by themselves don't look particularly attractive. Anyone know of any good examples of predator aquascapes they can link to for ideas? Or any ideas in general? I don't think planted would work to well due to the amount of waste that's created when he eats. Let me know!
