Whiptail catfish (Twig catfish)
Farlowella acus
Farlowella acus is that classic twig-looking whiptail that can sit on wood and basically disappear - it really does look like a little stick with fins. It is super chill and spends most of its time grazing and picking at surfaces, so it does best in a mature tank with stable water and plenty of stuff to cling to.

Gardner's killifish
Fundulopanchax gardneri
Gardneri are those little West African killies that look like someone painted neon speckles and flag-fins onto a 2-inch fish. The males will posture and flare at each other but its more drama than damage, and they will absolutely reward you with constant spawning if you give them mops or fine plants. Biggest things to know: keep a tight lid (they jump) and do not cook them warm - they do best in the low-to-mid 20s C.

Blue gularis
Fundulopanchax sjostedti
This is the big, flashy West African killifish with the ridiculous triple-point tail and electric blue-green body covered in red spotting. Males can be real attitude machines with each other, but if you give them room, cover, and a tight lid, they make an awesome centerpiece fish that will absolutely demolish live and frozen foods.
