personally i think you should go for what i did and do a oddball tank, i have black ghost knifefish & cuvier bichir which are the most awsome fish every and just to make sure no snails start getting in there a group of yoyo loaches thats what my tank fish wise contains and i think its a great oddball tank and is always intresting to watch!!
