I collect rocks from local streams. I bring a backpack lined with a garbage back and some latex gloves. When I get them home I boil them in a stock pot, and then place them in my aquarium. Rocks, that are too big to boil I have soaked in bleach water and then rinsed well. I've been using local rocks for years and never had any problems. I love the price, but I also find them very beautiful. Phil Edwards implied that biotopes with multiple colors of rocks, or a mix of smooth and irregular edges is inaccurate. I find red, orange, brown, black, and even a little green all in the same spot. I also find very smooth, rounded rocks along with jagged, broken rocks with no roundness to them. I even have a nice, big piece of petrified wood. Maybe that would make some biotopes look wrong, but apparently Issaquah is very diverse :) -----Original Message----- From: gsas-member-bounces@thekrib.com [mailto:gsas-member-bounces@thekrib.com] On Behalf Of Matt Staroscik Sent: Thursday, January 12, 2006 12:46 PM To: Greater Seattle Aquarium Society member chat Subject: Re: [GSAS-Member] Albino Bristlenoses Update On the subject of these fish, does anyone have a good source of rocks to make caves out of? My tank has plants and driftwood, but it doesn't have any really good hiding places now that I look carefully. The best option is the shadowed underside of a driftwood branch, a location my new male bristlenose has already found. But clearly now, I need more caves for my various critters. I think I will pick up some slate from Denny's Pet World for starters, LMK if you have other ideas.
