Uaupesi Apistogramma - Apistogramma uaupesi : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Uaupesi Apistogramma (Apistogramma uaupesi) is an alluring yet demanding species of Dwarf Cichlid originating from the very soft, acidic waters of the Rio Negro system. Due to their specific habitat requirements, these fish are best suited for seasoned Apistogramma enthusiasts, as they can be quite sensitive.
In terms of behaviour, Uaupesi Apistogrammas are generally peaceful but may become territorial during breeding. Optimal care involves housing either a single pair or, in larger tanks, one male with multiple females to form a harem structure. The females tend to establish individual territories, necessitating an aquarium layout with plenty of visual barriers. Suitable tankmates include Corydoras Catfish, Hatchetfish, Pencilfish, small Tetras, and Plecos.
Creating the right aquarium environment for Uaupesi Apistogrammas involves soft, acidic water and a biologically mature setting. A dark substrate, dense vegetation, and ample hiding places using rocks, driftwood, and coconut shells are ideal. Floating plants are beneficial for light diffusion, and peat-based filtration along with dried Indian Almond Leaves can help maintain preferred water conditions. Due to their jumping tendencies, a securely fitted lid is crucial.
These fish display remarkable colour variation. Males typically have a blue face with a distinct black stripe along the spine and sides that shimmer in blue or purple. Their head and gill covers feature red and blue spots, and the fins are often reddish. Females are less colourful, with a bluish tint and lighter orange-yellow bellies.
Males are known for their ability to rapidly change body markings and fin positions, especially during displays with females or confrontations with rivals. Their dorsal fins and dark body markings, including the abdominal dots and lateral line, can change dramatically, with the lateral line's intensity varying from prominent to nearly invisible.

Sexual Dimorphism
Determining the sex of Uaupesi Apistogrammas is relatively straightforward, thanks to their distinct sexual dimorphism. Males are recognized by their vibrant colours and slightly smaller size compared to females.
Male Uaupesi Apistogrammas feature elongated rays in their dorsal fins, prominent and large ventral fins, and typically rounded caudal fins. In contrast, females are larger and display more subdued colouration. They typically have a soft yellow hue or a less intense colour scheme and can be identified by their rounder fin shapes.
During the breeding season, female Uaupesi Apistogrammas undergo a striking colour change, transforming to a much brighter yellow, which is quite different from their usual appearance. This dramatic shift in colour during breeding is a key aspect of their mating behaviour and adds an intriguing dynamic to their overall appearance.

Natural Habitat
The Uaupesi Apistogramma, a species native to the Amazon Basin, thrives in the exceptionally soft and acidic waters of the Uaupés River and the upper Rio Negro in Brazil, as well as in tributaries of the upper Río Orinoco in Colombia and Venezuela. Their natural habitats are distinguished by an abundance of leaf litter and dense overhanging vegetation.
These fish are commonly found along rocky shorelines and can also be observed in areas with open sandy bottoms. The specific environmental conditions of these regions, including water chemistry and substrate composition, play a crucial role in the lifestyle and survival of the Uaupesi Apistogramma.
Breeding
Uaupesi Apistogrammas reproduce through substrate spawning, laying their eggs in hidden crevices or protected areas within the aquarium. The mature males establish territories, often showing aggression towards other males while being more accommodating to multiple females.
After spawning, the male's role expands to defending a broader territory and attracting additional female mates. The female, meanwhile, focuses on the careful nurturing of the eggs and later, the fry. She remains vigilant in guarding the eggs, ensuring their safe development.
The time it takes for the eggs to hatch varies with water temperature, typically between 36 to 72 hours. Once hatched, the fry quickly becomes free-swimming, a crucial developmental stage occurring a few days after hatching. During this period, the female's attentive care is crucial for the fry's survival and growth, highlighting the importance of parental roles in the life cycle of Uaupesi Apistogrammas.
Diet & Feeding
Uaupesi Apistogrammas exhibit an omnivorous diet, showcasing their ability to consume a wide variety of foods. In their natural environment, they feed on algae, organic matter, and small invertebrates, including insects, worms, and crustaceans, demonstrating their adaptability and diverse dietary preferences.
In captivity, these Apistogrammas readily adjust to a range of commercially prepared foods. They can be fed high-quality flakes, pellets, and granules suitable for tropical fish. To more accurately reflect their natural diet, incorporating live and frozen foods like bloodworms, brine shrimp, and daphnia is recommended. This approach ensures a balanced diet that supports their health and replicates the nutritional diversity they experience in the wild.
