This Petsmart tank includes everything filter with media and pre filter sponges, lid, light, gravel, background and a way to apply it and a net. I highly recommend getting this at your local petsmart for $40 on sale right now but in stores only! It’s a great deal I would get it if I had the space. The price is different online then in stores. The perfect shrimp tank on a budget!
