55 gallon fishtank on homemade wooden stand.Has undergravel filter and powerhead,as well as gravel, hood, and heater.The stand is sturdy but my cats used it for a scratching post so it could use a new leg or two,but is sturdy and holds the weight with no problem.. The shelf underneath is good for knicknacks or storage.I've moved to a trailer and its just too big so i was forced to downsize.
