Planted tank, remodeling overall look 29 gallons, Eclipse 3 filtration hood, 2 inches substrate. I've had the tank since May now and have added the large piece of wood and replaced some plants in the last couple days. I have rummy-nose and cardinal tetras, a rainbow shark, and kuhli loaches. I love the large piece of wood because it is actually concave upwards underneath and forms a cave with multiple openings (couldn't catch that in a pic though). I'm in the process of removing the (volcano?) rock and replacing it with wood. I'm also going to look into smaller substrate. I plan on buying a larger tank in January and really want to aquascape that, so this may become a holding/growing tank for me.
