The yellow-tailed Congo tetra, Alestopetersius caudalis, is an alestid from the lower Congo region, recorded upriver as far as the Irebu channel. Also traded as the 'yellow-finned', 'yellowtail' or 'blue Congo' tetra, it is occasionally bred commercially, though not on the scale of its better-known relative Phenacogrammus interruptus. Adult males develop extended median caudal-fin rays, and the narrow dark lateral stripe broadens markedly on the caudal fin.

The leopard bushfish, Ctenopoma acutirostre, is an anabantoid from the middle Congo River basin, from Malebo Pool upstream to Boyoma Falls. Often sold as 'spotted climbing perch', it mimics leaves and other debris to stalk its prey, much like the unrelated South American leaf fish. Exceptionally hardy and long-lived, it can survive for over 15 years and makes an ideal species for the newcomer to 'oddballs'.
