I copperband gets large, much to large for a 29g tank. Secondly, they often times come in with some type of parasite and the stress of living in such a small tank will only make the fish more prone to ich or any other parasite. Please save the fish and your own money, i would hate to see either one go to waste. You will not have any type of long term success with a copperband in a 29g tank. Save the money and just get a few peppermints like everyone has recommded.
