PERUSING THE aisles of your local LFS for inspiration can be a minefield when you have a spare, generously-sized tank.

It can be a trip into the unknown or the chance to rediscover an old friend — at least that’s how it is for me. But what is it that draws you in? Maybe you’re a fan of the billowing fins of a showy Betta, or the eclectic adornments of a Steel-blue killifish, Fundulopanchax gardneri. If you’re anything like me, the chances are you make a beeline for something completely out of the ordinary, a fish that really fuels your curiosity.
