Additional Information

There are South American killifish which are not annuals.  They belong to two (2) genus pituna and rivulus which has ninety-seven (97) species.


Of the Rivulus genus species the most common are:  Rivulus agilae (7 populations),  Rivulus iridescens (2 populations), Rivulus magdalenade-Columbia), Rivulus rectocaudatus ( DWTS 08-03),

Rivulus rubrolineatus (2), and Rivulus xiphidius (5 populations); just to name a few of the more common species, if you connect with members of the American Killifish Association (AKA), who specialize with the non-annual South American killifish.


Being non-annuals, these are a little easier to keep and breed, but are not commonly found in the aquarium hobby.
