Macmaster’s Dwarf Cichlid — Apistogramma macmasteri: Habitat and Care

Macmasteri is a fairly deep-bodied Apistogramma, with a dark lateral pattern, a conspicuous tail-base mark and variable red and blue colour. Adult males normally develop larger, longer fins than females. The main portrait represents restrained domestic coloration without certifying a named line. Young or subordinate males may be pale, so a small colourless individual is not automatically female.

Apistogramma viejita remains a distinct species. Trade labels have often been confused, and Red Mask or Super Red describes appearance rather than establishing ancestry. Do not identify a fish solely by how much red it shows. Ask for the breeder’s identity and provenance, use several adult characters and keep uncertain stock labelled honestly rather than silently merging the two species.

The species is recorded from the Guaytiquía and Metica systems of Colombia’s upper Meta drainage, within the Orinoco basin. That geographical identity matters when comparing accounts or purchasing locality fish. A selected aquarium colour form should not be assigned a wild collecting place simply because it resembles a photograph.

Translate the bottom-oriented habitat use into separate sheltered spaces, fine substrate and reliable maintenance access. A domestic aquarium can include suitable plants without pretending every ornamental plant occurs at the collection site. Distinguish an effective home layout from a documented biotope, and let the actual source of the fish guide any specialist water preparation.

Seriously Fish quotes 45 × 30 cm for a pair, whereas Christian Splettstößer’s detailed keeping account recommends at least 80 × 30 cm for ordinary pair maintenance. Prefer the latter footprint for a home display: it gives more scope to split feeding positions and break sightlines. These are different husbandry judgements, not interchangeable guarantees of compatibility.

The same breeder describes considerably more floor for a trio and aggression between females as well as males. Do not add a second female as a routine cure for chasing. Use a single male for a non-breeding display if appropriate, or an actually compatible pair with prepared separation. A fish living permanently behind the heater or at the surface has not found an acceptable territory.

Published temperature guidance is 24–28°C, with the first-hand keeper reporting good routine results near 25°C. Around 25–26°C offers a practical maintenance choice. A pH around 6.0–6.8 is also consistent with that account. The specialist summary gives 0–5°dGH; soft water is sensible, but the lower endpoint is not an instruction to pour untreated pure RO water into the aquarium.

Know both GH and KH and prepare replacement water before use. Retain stable conditions for established captive fish rather than repeatedly correcting a decimal. Keep biological filtration mature and surface exchange visible, with a quieter bottom zone. Remove food deposits from behind shelters and make regular partial changes according to the actual waste load.

For the sheltered lower layout, compare Palmyrah Pod Half (Arecaceae sp.) – Natural Botanical Cave with Blackwater Botanical Box – Pods, Leaves, Cones & Large Feature Piece. Inspect the actual pieces for adult entry, turning space and accessible exits; position them beside an open feeding patch rather than making every route pass through one refuge. A mixed box provides material to choose from over time, rather than a quantity to add all at once.

Peaceful upper-water companions can be considered in a properly sized aquarium when their water and temperature needs agree. Do not interpret the word dwarf as permission to stack several cichlid territories on the same floor. Other bottom residents may repeatedly enter the defended area even when they are not themselves aggressive.

Small shrimp and young fish may be prey. A previously tolerated companion can become a target during reproduction. Observe the whole aquarium, including routes behind roots, and separate if a fish cannot feed or rest. The links to agassizii and cacatuoides help compare different care plans; they are not a recommendation for a mixed-Apistogramma display.

Eggs are attached within a sheltered site, often to the ceiling of a cavity. The female tends eggs and larvae, and can defend the surrounding space strongly. A male may need removal if the arrangement becomes unsafe. Do not repeatedly lift a cave to count eggs or assume that spawning proves a permanently compatible pair.

Have small first foods such as Artemia nauplii available for free-swimming young, along with a protected intake and a separate grow-out plan. Feed within reach while limiting waste. A community spawn is not assurance that fry will survive: companions and older siblings can remove young. Repeated loss needs observation of fertilisation, water quality and behaviour rather than an automatic increase in acidity or botanical quantity.

When one fish is hiding or thin, inspect access to food and low-level aggression before blaming the water’s colour. Verify temperature, ammonia and nitrite, and look for trapped waste in the sheltered areas. Rapid breathing, damaged fins or continuous pursuit require a prompt practical response rather than waiting for a numerical sex ratio to solve matters.

Keep a record of source identity, settled water conditions and any actual breeding observations. Avoid changing diet, substrate, filter and chemistry together. Sound care comes from an identifiable fish in a maintainable territory; no leaf, pod or colour-form label can guarantee health, pair compatibility or breeding success.
