Reitzigi Opal

Overview

An aquarium form combining the characteristic yellow head of reitzigi with the enhanced opalescent blue body sheen. Created through crossing of reitzigi and borellii Opal forms; valued for combining both color traits.

Appearance

Shared with the species: Reitzigi Dwarf Cichlid

The most distinctive feature of Apistogramma reitzigi is the brilliant yellow head of the male, which contrasts strongly with the iridescent blue-green scales of the body. The dorsal fin is erect and pointed, often showing yellow and blue coloration, while the caudal fin may have rounded extensions with blue edging. Females are considerably smaller and much less vibrant, displaying a yellowish base with faint markings. Male body length reaches about 6–7 cm, with females remaining smaller.

Care

Shared with the species: Reitzigi Dwarf Cichlid

Care requirements for Apistogramma reitzigi are essentially identical to those of A. borellii as both forms are closely related. A tank of at least 60 liters with soft sandy substrate, caves, flower pots, and dense planting is recommended. Water parameters should be pH 5.5–7.0, hardness 2–12 dH, and temperature 20–26°C; soft, slightly acidic water is preferred for breeding. Weekly partial water changes of 25–30% are important to maintain optimal water quality. A secure lid is essential as these fish will occasionally jump.

Feeding

Shared with the species: Reitzigi Dwarf Cichlid

Apistogramma reitzigi is an omnivore that accepts a wide variety of foods. High-quality dry foods including flakes and small pellets form the dietary base, supplemented by frozen or live foods such as bloodworms, daphnia, artemia, and mosquito larvae. Live foods enhance coloration and encourage breeding behavior. Feeding once or twice daily in small portions is recommended to avoid water quality issues.

Compatibility

Shared with the species: Reitzigi Dwarf Cichlid

Apistogramma reitzigi is a peaceful community fish when kept with suitable tankmates. Best companions include small tetras, rasboras, pencilfish, hatchetfish, and corydoras. During spawning periods the fish becomes defensive and territorial, so adequate hiding spots are important. Avoid housing with aggressive or significantly larger fish species.

Breeding

Shared with the species: Reitzigi Dwarf Cichlid

The breeding behavior of Apistogramma reitzigi mirrors that of A. borellii; it is a cave spawner that forms a nuclear family unit during reproduction. The female selects a suitable cave and deposits 40–80 eggs, which she guards zealously while the male patrols the perimeter. Incubation takes approximately 48–72 hours and the fry become free-swimming within a week. Raising the temperature slightly to 24–26°C and providing very soft, acidic water stimulates spawning. The male should be removed if fighting with the female occurs.

Fun facts

Shared with the species: Reitzigi Dwarf Cichlid

Apistogramma reitzigi was scientifically described by Ahl in 1931, making it one of the earlier Apistogramma species to enter the aquarium hobby. Despite being treated as a synonym of A. borellii in modern ichthyology, it remains widely available under its own name in the aquarium trade around the world. The 'reitzigi' name honors an early 20th-century aquarist who contributed to the collection and study of South American cichlids.
