Apistogramma Borelli "Opal"

Apistogramma borellii "Opal" (Opal Dwarf Cichlid)

The Apistogramma borellii "Opal" is a stunning color variety of the Yellow Dwarf Cichlid, prized for its shimmering blue iridescence, golden-yellow accents, and graceful finnage. Native to the slow-moving streams and wetlands of southern South America, this peaceful dwarf cichlid is well-loved for its vibrant appearance, gentle temperament, and adaptability, making it an excellent choice for planted aquariums and peaceful community setups.

Apistogramma borellii "Opal" are curious, intelligent fish that spend much of their time exploring the lower levels of the aquarium among plants, driftwood, and rockwork. Males develop brilliant metallic blue coloration with extended fins, while females remain smaller and display bright yellow breeding colors when caring for eggs or fry. Compared to many other Apistogramma species, Borellii are relatively mild-mannered, making them one of the best dwarf cichlids for community aquariums with compatible tank mates.

These dwarf cichlids thrive in well-planted aquariums with soft to moderately hard water, gentle water flow, and plenty of natural hiding places. A sand substrate, driftwood, caves, and dense vegetation encourage natural behaviors while providing security. Although tolerant of a wider range of water conditions than many Apistogramma species, they appreciate stable water quality and a varied diet of high-quality micro pellets, frozen bloodworms, brine shrimp, daphnia, and occasional live foods to maintain their health and vibrant coloration.
