Additional Information

There are one hundred and four (104) species of South American annual killifish in thirteen (13) genus.  They Austrolebias (36 species), Cynolebias (11), leptolebias (7). megalebia (5), micromoema (1), moema (8). nemotolebias (2), plesiolebias (5), pterolebias (3), rachovia (5), renova (1), spectrolebias (44), and terrontos 1


Like the African annual killifish (Nothobrachius genus) these are not recommended as a first killifish and certainly not for someone new to the hobby.


Many of these South American annuals (SAA) have egg incubation of a few month, to 6 months or more, with some needing an alternation of wet and then dry periods.


--------------------------------------

Special Note:


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.
