Description: 90 gallon 48x25x18 / 300 WATT All-Glass Aquarium submersible heater / upgrated from cascade power 300 to Penn-Plax Cascade canister filter 1000 / Has 2 small bubble stones and a long bubble strip under sand with Aqua Culture pump. Started this tank in November of 2005 when I was pregnant with my daughter to keep me busy. First it was just the two common goldfish and has grown from there. Still really new and learning from my mistakes. Like I said, tank isn't that old and there are more fish to come as I learn., also has lava rocks, driftwood, 150 pounds of sand, and 80 pounds of rock that came from our creek. And the background is wallpaper mosaic of water.
