Hypselecara coryphaenoides
Hypselecara coryphaenoides
The unobtainable 'Rio Negro Chocolate Cichlid' (20-25 cm). Direct (and often confused) cousin of H. temporalis. Less known and widespread, this cichlid shares the exceptional mildness of the family and the high disc shape, but differs in the rigid need for amber and acidic waters. Features darker and more purplish chromatic shades. A jewel for peaceful and unplanted Blackwater biotopes.

Profil de poisson
- Tempérament
- Semi-aggressive
- They are surprisingly peaceful and easygoing compared to other South American cichlids of similar size. They move slowly and deliberately, observing their environment. Aggression is typically only displayed when defending their fry during breeding.
- Régime alimentaire
- Omnivore
- They are omnivores with a hearty appetite for both plant and animal matter. Offer a staple diet of high-quality cichlid pellets, supplemented with earthworms, shrimp, and blanched vegetables. Variety ensures they maintain vibrant coloration and robust health.
- Espérance de vie
- 10-12 years
- Taille adulte
- 25 cm
- Ratio des sexes
- Pair
- Males generally grow significantly larger and develop a pronounced nuchal hump on their forehead as they mature. Females remain slightly smaller and lack the prominent hump. Keeping them in a group as juveniles allows a natural pair to form.
- Fréquence d'alimentation
- Twice daily
- Adults should be fed once or twice a day with carefully measured portions. Do not overfeed, as they are prone to overeating and subsequent digestive issues. Fasting them one day a week can be beneficial for their digestion.
- Charge biologique
- Medium to High
- As a large cichlid, they produce a considerable amount of waste, equating to a high bioload. Strong, oversized filtration systems are required to handle their output effectively. Consistent and substantial weekly water changes are a strict requirement.
- Courant
- Stagnant
- They favor sluggish to moderate water flow, typical of their natural Amazonian backwater habitats. Turbulent currents should be avoided to minimize stress. Gentle circulation that keeps the water highly oxygenated is ideal.
- Risque de saut
- Yes
- While not notorious jumpers, their sheer size means sudden startled movements can cause them to breach the surface. A sturdy, weighted aquarium lid is recommended. This prevents water splashing out and ensures the fish remain safely inside.
- Reproduction
- Oviparous
- They are substrate spawners that form strong monogamous pair bonds. The female lays eggs on a flat, cleaned stone or piece of driftwood. Both parents are fiercely protective of the eggs and the resulting fry.
- Compatibilité et compagnons
- Semi-aggressive
- Despite their large size, they are relatively mild-mannered for cichlids. They can be kept with other peaceful large cichlids, large characins, and sizable catfish. Avoid keeping them with very small fish that could easily fit into their mouths.
- Niveau dans le bac
- Middle
- They utilize the middle and lower levels of the aquarium. The tank setup should include large open swimming areas alongside complex driftwood structures for shelter. They may occasionally rearrange small decor or uproot delicate plants.
