Apistogramma elizabethae, also known as Elizabeth's Apistogramma or Elizabeth's Red Dwarf Cichlid, is a stunning and relatively rare species of dwarf cichlid native to the upper Rio Negro basin in Brazil. Species Overview Scientific Name: Apistogramma elizabethae Size: Up to 5 cm (2 inches) Lifespan: ~5 years Temperament: Semi-aggressive, especially during breeding Difficulty: Intermediate to advanced aquarists Natural Habitat Found in slow-moving tributaries and leaf-litter-rich creeks of the Rio Uaupés and Rio Içana in Brazil Prefers soft, acidic water (pH 4.0–6.0, GH 2–8, temperature 22–29°C). Substrate is typically dark and sandy, with dense vegetation and leaf litter providing cover and spawning sites Aquarium Setup Tank Size: Minimum 45×30 cm base for a pair; larger for groups Substrate: Fine sand is ideal for natural sifting behavior Décor: Include driftwood, rocks, coconut shells, and dried leaves (e.g., Indian Almond or alder cones). Lighting: Dim lighting with floating plants to diffuse light. Filtration: Gentle flow; sponge filters are preferred. Water Changes: Regular partial changes to maintain low nitrate levels. Diet Omnivorous: In the wild, they eat algae, detritus, and small invertebrates In captivity, feed: High-quality flakes or pellets Live/frozen foods: bloodworms, brine shrimp, daphnia Variety is key to maintaining health and coloration Breeding Behavior Substrate spawners: Eggs are laid in crevices or caves Males: Defend territory and court multiple females. Females: Guard eggs and fry, becoming brightly yellow with black markings during breeding Incubation: 36–72 hours depending on temperature. Fry Care: Sensitive to water chemistry; feed small meals multiple times daily and perform gentle water changes Sexual Dimorphism & Coloration Males: Blue-grey base with vivid blue and orange-yellow highlights; elongated dorsal rays and spade-shaped tail. Females: Olive-colored normally, but turn bright yellow with black spots during breeding Variants: Includes “super red” and blue-marked forms depending on collection locality
