带纹丽体鱼 · Oaxaca Cichlid

Overview

Vieja zonata is a robust large cichlid with moderate aggression. Plants dominate its natural diet, yet small fishes may still be swallowed. Pairing and mixed housing both require ample space and continued observation.

Distribution & habitat

It appears endemic to Mexico's Tehuantepec drainage.

Aquarium setup

Secure rocks, roots, and branches because the fish rearranges furnishings. Sand or fine gravel and effective filtration are suitable. Arrange the aquarium so each occupant has space to withdraw and establish an area.

Diet & feeding

Vegetable ingredients such as spirulina or algae wafers should remain important because the natural diet is mainly herbivorous. Cichlid pellets, live bloodworms or Artemia, and supplementary shrimp or mussel flesh are also accepted.

Behaviour & compatibility

Large aquaria may permit similarly sized robust cichlids. Growing compatible candidates together from juveniles may improve prospects without guaranteeing success. Any fish small enough to fit its mouth is at risk, regardless of that companion's temperament.

Sexual dimorphism

Males become larger and more colorful and develop a forehead hump with dorsal and anal extensions.

Breeding

Establishing coexistence within the pair is the main obstacle; compatible fish generally spawn readily. A large stone or cave surface is cleaned before laying. Separate the female if male aggression becomes excessive. Eggs hatch after two to three days, and young swim freely about four days later. Artemia nauplii can be followed by microworms, fry foods, and crushed prepared food. Remove juveniles when parents preparing another spawn begin rejecting them.

Notes

The species is uncommon in ordinary trade and more often available through specialist dealers. Hardiness does not remove the need to monitor pair relationships and maintain water quality.
