This streamlined, beak-mouthed, saber-toothed species has been in the hobby for nearly 100 years. One of the livebearers “with character,” it is undoubtedly a species for the specialist who likes something a little different. Two subspecies are sometimes recognized: B. b. belizanus and B. b. maxillosus (Yellow Pike Top Livebearer) from the Yucatan in Mexico. Some authorities doubt the validity of the second subspecies, however.
