红头丽体鱼 · Redhead Cichlid

Overview

The colorful Vieja synspila is a large, moderately aggressive cichlid. Breeding success often depends first on maintaining a compatible pair, especially protecting the female from excessive pursuit.

Distribution & habitat

It is native to the Usumacinta basin across Mexico, Guatemala, and Belize. Still or slow lowland rivers and lakes are typical. Mildly brackish sites are occasionally used, but long-term tolerance there is uncertain.

Aquarium setup

Secure rocks, roots, and branches because the fish rearranges its surroundings. Sand or fine gravel is suitable, lighting is flexible, and dependable filtration is important. Provide screening and usable territories rather than a bare open enclosure.

Diet & feeding

The wild diet is primarily plant-based. Quality cichlid pellets can be supplemented with shrimp, mussel, and white fish, but spirulina or algae-based foods must retain an important place in the menu.

Behaviour & compatibility

Large robust Central American cichlid communities may work with ample separate areas and cover, though success is never assured. Bonded pairs often coexist, but the female still needs monitoring for harassment.

Sexual dimorphism

Males grow larger, become more colorful, develop a forehead hump, and have extended dorsal and anal fins.

Breeding

A pair clears a large stone or cave surface before laying. Male aggression during spawning can become excessive, requiring separation. Eggs hatch in two to three days, followed by about four days before free swimming. Start fry on Artemia nauplii, progressing to microworms, fry foods, and crushed pellets. Parents provide strong care but may reject an earlier brood when ready to spawn again; move juveniles then.

Notes

Different scientific spellings appear on trade labels, making a complete identification record useful. Occasional brackish-water occurrence does not mean salt is required for aquarium maintenance.
