I have a 10 gallon tank lying around, so i cleaned it out real good and I have a HOB filter on it, and i put in some new gravel and water in today, been running the filter to clear up the water today. I just got a 30 gal too, and I wanted to keep this 10g as a spare tank, so imma put some small stuff in it after it cycles. I wanna keep this cheap/free as possible, do I need a hood/lamp?
