Not sure if this will work very long term, but if I do water changes frequently enough I think it will. The only I still plan to add is a small piece of mopani wood that I have cleaning/curing at the moment. Haven't given the fish a name yet... I'm pondering a really small in tank filter, I have a duetto 50 that I'm not using but it seems a little big fir this, maybe a sponge filter, maybe nothing.. What are your thoughts?
