Andinoacara sp. 'Orinoco'

Overview

Apparently undescribed, Andinoacara sp. ‘Orinoco’ is relatively mild for a cichlid of its size but retains territorial males, especially around spawning. Established water quality, adequate room, and restrained current are central to care.

Distribution & habitat

Collected somewhere within the Orinoco basin, it is presumed to come from Venezuela. Slow or still, structurally complex habitats with roots and leaf litter are suggested rather than confirmed. Rainy-season changes in the basin can strongly alter depth, flow, and turbidity.

Aquarium setup

Soft sand, subdued light, wood, and scattered roots suit the display. Add smooth flat stones as potential spawning sites and allow significantly more room for multiple pairs. Never introduce fish into an immature aquarium. Effective external or sump filtration and weekly changes of roughly 50–70% support stability.

Mechanical filtration should intercept disturbed particles before sand repeatedly enters the mechanism. Distribute filter returns to avoid excessive current. Poor maintenance or feeding may accompany head and lateral-line erosion or stunted growth.

Diet & feeding

An easily fed omnivore, it can receive quality sinking dry food with regular live or frozen bloodworms, Artemia, and similar additions.

Behaviour & compatibility

Males defend territories, particularly while breeding, despite the species’ comparatively mild disposition. Very small fish may be eaten. Other cichlids can be considered only where space allows territorial separation.

Sexual dimorphism

Males grow larger and commonly develop extended unpaired fins. Their color becomes especially strong in breeding condition.

Breeding

Both parents care for eggs laid on a surface. Raising at least six juveniles together and removing surplus fish as pairs form is a proven approach. Eggs reportedly hatch after about three days, with fry swimming freely around day six.
