Mendez Apisto (Apistogramma mendezi) Care Guide
Apistogramma mendezi is a South American dwarf cichlid; this guide covers its habitat, water parameters, diet, compatibility and breeding.
Compiled by Aquairi from published sources · Published · Updated
Overview
Apistogramma mendezi is a dwarf cichlid of the family Cichlidae, described by Romer, 1994. It is native to the Negro River basin of the Amazon River system in Brazil.
Taxonomy
- Family: Cichlidae
- Scientific name: Apistogramma mendezi
- Describing authority: Romer, 1994
Habitat
The Negro River basin of the Amazon River system in Brazil forms the natural range of this species. It inhabits soft, acidic blackwater stained amber by tannins from decaying leaf litter, with little water movement. Apistogramma species typically occur in shallow water, often less than 40 cm deep.
Tank requirements
- Minimum tank volume: 80 L (~21 US gal)
- Temperature: 26-30 °C (79-86 °F)
- pH: 4-6
- GH: 1-3 °dGH
- Adult size: 5-8 cm
- Lifespan: 3-5 years
Diet
Apistogramma are omnivores that lean toward micropredation, feeding on aquatic insect larvae, small invertebrates and other tiny prey in nature. In the aquarium they take live and frozen foods such as bloodworms, brine shrimp and water fleas, and many specimens also accept prepared foods.
Compatibility
This is a semi-aggressive, bottom-oriented dwarf cichlid. It is best kept with peaceful upper- and mid-water dither fish such as Cardinal Tetra, Rummy-Nose Tetra, Sterbai Corydoras, Hatchetfish. Housing more than one male of the same species, or combining it with angelfish or larger aggressive cichlids, is discouraged because of territorial conflict, particularly during breeding.
Breeding
Apistogramma are cave spawners. Eggs are laid on the ceiling of a cave or sheltered cavity, and the female tends the eggs and fry while the male guards the wider territory. Soft, slightly acidic water supports spawning.
Conservation status
IUCN Red List: Least Concern (LC), assessed 2018.
Apistogramma mendezi Breeding Guide
Overview
Apistogramma mendezi is native to the lower Rio Negro basin in northwestern Brazil, around Santa Isabel do Rio Negro and Sao Gabriel da Cachoeira, with the type locality at the Rio Salgado near Barcelos. It inhabits pristine blackwater tributaries and flooded forest where the water is darkly stained, over sand or mud with leaf litter and woody debris. It belongs to the A. paucisquamis complex within the A. bitaeniata group. Seriously Fish describes it as a substrate spawner laying eggs in crevices or cavities among the decor.
Sexing
Males are larger, more colourful and develop more extended fins than females. The brighter, more elaborately finned male contrasts with the smaller, plainer female, which assumes broodcare coloration when tending eggs.
Conditioning
As a carnivorous dwarf cichlid, A. mendezi is conditioned on small live and frozen foods. Stable, soft blackwater conditions and consistent feeding bring females into spawning condition. Wikipedia notes that nearly all Apistogramma spawn in crevices, typically in holes in sunken logs or branches or in leaf-litter aggregations, so providing such structure encourages the female to select a spawning site.
Breeding Setup
Provide caves or crevices and reproduce the blackwater habitat with leaf litter and wood. Seriously Fish lists breeding parameters of 23-29 degrees C, pH 4.0-6.0 and hardness of 18-54 ppm, reflecting its strict soft, acidic requirements. In smaller tanks the male may need to be removed because of female aggression during broodcare.
Spawning Behaviour & Trigger
The female lays her eggs inside a chosen cavity and assumes primary responsibility for the eggs and fry. Very soft, acidic water is the key condition for viable spawning.
Egg & Fry Care
The female tends the clutch and leads the free-swimming fry while the male defends the surrounding territory. No species-specific egg count is published by the consulted sources.
Common Challenges
Maintaining the very soft, acidic blackwater this species demands is the principal challenge, alongside female aggression toward the male during broodcare in confined tanks. Wikipedia notes that across the genus water conditions affect offspring sex ratios, with warmer water and, in some species, lower pH producing more males, so stable, moderate parameters help yield balanced broods.
