I recently got my 30 gallon tank filled back up/re-cycled/re-stocked with fish...and I had forgotten how much fun it is to just sit and watch my aquarium. Its very... relaxing.
That dark thing under the fake tree root is a chunk of driftwood for my pleco. It used to sink, but I took it out for a little while, and now I'm just too lazy to get it to really sink again so its just wedged under the root to hold it in place.
