匠丽体鱼 · Pearlscale Cichlid

Overview

The large pearlscale cichlid Herichthys carpintis displays blue-green tones and reflective flank markings. Basic care and reproduction are relatively manageable, but digging, territorial behavior, and male attacks on partners require adequate space and a ready means of separation.

Distribution & habitat

It originates in northern Mexico, particularly lagoons near the mouth of the Panuco drainage.

Aquarium setup

Use rocks and wood to create territorial divisions while retaining open swimming space. Rooted plants are easily displaced by excavation. A substantial aquarium with effective filtration is necessary for long-term care; juvenile size should not determine permanent housing.

Diet & feeding

This omnivore usually accepts prepared food readily. Base meals on a quality cichlid pellet, varying the menu with live or frozen items such as Artemia. Vegetable-rich or spirulina flakes provide useful regular supplements.

Behaviour & compatibility

Territoriality can be pronounced, especially during reproduction, and direct aggression is possible. Small fishes are regarded as food. Temporary tolerance or a companion's speed should not be treated as proof of safety.

Sexual dimorphism

A dark female dorsal-fin blotch is a useful clue. Assess appearance alongside reproductive behavior rather than immediately combining adults on the strength of one marking.

Breeding

Compatible fish display to one another, clean a smooth rock, and develop a pale front half with a dark rear half. The female lays eggs and the male follows to fertilize them. Both parents move water across the clutch with their fins.

Hatching can occur within roughly two days, after which larvae may be transferred to nursery depressions. Swimming follows up to about a week later. Keep a divider available throughout: a male can turn on his female even after the pair has spawned.

Notes

Texas-cichlid trade labels are applied inconsistently to different species, including this one. Check scientific identity and provenance rather than relying solely on the sales name.
