Halfbeaks may be livebearers, but that doesn’t mean they’re easy to keep or breed. Adult halfbeaks are sensitive to rapid changes in water chemistry and fussy about their food, so simply keeping them alive can be tricky. Moreover, halfbeaks are shy but territorial fish that fight among themselves, and they also are easily bullied by larger or more aggressive species. While they mate just as readily as other livebearers, females are prone to miscarry their broods, and the fry can be difficult to feed. The bottom line is that halfbeaks have a reputation for being difficult fish best attempted by the prepared aquarist.
In reality, once you accommodate their little idiosyncrasies, you’ll discover that halfbeaks are adaptable fish that will tolerate a wide range of water chemistry parameters (as long as the chemistry stays consistent) and get along with most community fish. Breeding them is a challenge, but once the fry are feeding well, they’re hardy and grow quickly.
