Let us take a look at our first contender Pa- rachromis dovii. They occur in rivers and lakes from Honduras, Nicaragua and Costa Rica, from the Aguan River (Honduras) in much of the crater Lakes (Nicaragua),to the Moín River (Costa Rica); Pacific slope from the Yeguare River (Honduras) to the Bebedero River (CostaRica). Named by Günther after the fish collector John Dow, this cichlid is the largest in the Parachromis complex reaching a size of 63cm- 24” and over. Parachromis dovii are piscivores in the wild, but will except other commercial foods such as large cichlid pellets or food sticks. As they are pis- civores, keeping them with other cichlids and fish of a much smaller size certainly isn’t recommend- ed; Neetroplus nematopus is one their main sta- ple in the Nicaragua crater lakes. Young semi adult fish maybe kept with other cich- lids of similar size in a large tank, but in reality they are recommended as a single species only. I personally wouldn’t keep a pair in anything less than 300g aquarium. They are big powerful cich- lids that will easily dominate a tank! Spawning is fairly straight forward with a compati- ble pair as they will clean and choose a large rock to deposit a large number of eggs. Compatibility is key with this species, as it is not uncommon for the male to turn on and kill the female. For this reason, spawning this species is recommended in a controlled environment using an egg-crate type divider. Our second contender; Caquetaia umbrifera (Umbee) again is the largest of the Caquetaia complex and largest of all Neotropical cichlids. C. umbrifera is known to attain a size of 80cm- 31”, so makes this a potentially massive cichlid! The Umbee is primarily a South American fish, as much of their range is in the Rivers of Columbia; notably the Río Atrato and Río Magdalena where there are noted to be different colour morphs. However, they also have a small range over the border into the Pacific slope of the Río Chucu- naque, Panama. Again the Umbee is primarily a piscivore, predator fish, so choose tank mates wisely. Like P. dovii, they are recommended for a species tank only where a compatible pair will have enough room to spawn. Umbee’s are open substrate spawners and will produce very large broods. Females when spawning look quite dis- tinctive from males as they turn a shade of yellow. © Stefan Zelinka http://www.stiffcichlids.com/ stiff/index.php 31
