This species was first imported for the aquarium hobby during the 1950s and was for many years misidentified and traded as Bedotia geayi, a valid, but different-looking congener native to the Mananjary River system, south of the range of B. madagascarensis. In terms of external characters, the two are most easily told apart by differences in colour pattern, particularly that of the unpaired fins, and some morphometric counts.
