Diagnostic Description

provided by Fishbase
Heros liberifer can be diagnosed from all its congeners by having the following characters: a pattern of several horizontal series of bright red dots on the lower half of the body sides (vs. absence of rows of red dots); distinct caudal spot in adult specimens (vs. caudal spot usually merged with bar 2 in adult specimens); and tiny dark dots on operculum and cheeks in adult males (vs. large dots or a vermicular pattern). It differs from adult specimens of the frequently syntopic Heros severus by narrow (vs. thick) lips, bar 4, which is not shortened, but extends from the anal fi n base onto the base of the dorsal fin (vs. bar 4 extending only slightly above the lower lateral line), by the first two anterior hemal spines, which are broader and partially connected (vs. the first three hemal spines connected), and a bright red (vs. brown to dark reddish) iris in live specimens (Ref. 114589).

Life Cycle

provided by Fishbase
Deposits eggs on vertical or sometimes on a horizontal surface. Hatching takes place approximately forty hours after spawning at 27° C water temperature. Both parents pick up the larvae to brood them orally (Ref. 114589).

Biology

provided by Fishbase
This species is adapted to lentic environment with flooded forest habitats as the typical biotopes. It has no narrow habitat requirement as it is observed not only in clearwater and extreme blackwater habitats, but also in whitewater habitats. It can thrive in a wide range of physico-chemical environmental conditions (pH 4.1-6.1; conductivity 4-15 μS/cm). It spawns in the flooded riparian forest during the flood season. At the start of the dry season, it leaves the riparian forests, which mostly dry up, and spends the low-water season among submerged logs, trunks and branches. During the low-water season, it usually seeks shelter in the crevices and gaps found between the boulders (Ref. 114589).

Heros liberifer

provided by wikipedia EN

Heros liberifer is a species of tropical cichlid native to lentic habitats, especially flooded forests, in the upper and middle Orinoco basin in South America.[1]

Up until 2014 the liberifer was incorrectly believed to be the previously defined H. severus that was defined in 1840 by Heckel[cite]. Heros severus can be differentiated by having a partially formed band unlike other Heros as well as having a red shoulders. This band was originally defined by Heckel however it was dismissed as an anomaly by Kullander(1986) in the collected species. With the finding of the true H. severum, Staek & Shindler officially classified the liberifer so as to make room for the true H. severus.[1]

Description

H. liberifer can be distinguished from other Heros species due to its small spots that form horizontal lines across the lower half of its body. Other traits of the liberifer are a caudal spot in adult specimen as well as, generally narrower lips than other species.

Aquarium trade

This species is uncommon in the aquarium trade.

The species generally found in the aquarium trade Heros efasciatus and its man-made color morphs(red and gold) as well as the unspecified H. sp.'rotkeil'.
