I've hatched RES eggs in a fishtank before. Used a 30 x 60, put in two bricks and a platform ontop of the two bricks, fill the tank tank with water to just above the bricks, put in fish tank heater and set temp, make sure heater is under water, put eggs in sealed container with moist vermicilite(sp) and seal lid, put container on platform, cover tank, add water every few days to keep the water level up and then you wait, and wait, watch paint dry, and wait and wait, watch grass grow, and wait, then if everything goes to plan the eggs should hatch
