- Common name: Emerald Cichlid, Chocolate Cichlid
- Group: Cichlids
- Habitat: South America; Peru, Colombia, Venezuela, Brazil; Amazon River basin
- Size: 25-30 cm.
- Biotope: Inhabits the slower-moving sections of rivers with muddy bottoms.
- Social behavior: Despite its large size it is generally a peaceful cichlid, but may become territorial during spawning. They can be kept with similar-sized fish in a suitably-large community tank.
- Diet: Omnivorous; In nature they eat almost everything, from small invertebrates to algae. In the aquarium they aren’t choosy eaters, any live, frozen and dry foods have taken.
- Breeding: Hard
- Tank: Minimum 250 litres.
- Population: 1 pair for 400 litres
- Decoration: Use sandy substrate and decorate their tank with some bogwood or roots and with some larger stones. Usually they will not dig out the plants. Place some flat rock vertically into the tank that can be act as spawning sites.
- Temperature: 25-30 °C
- pH: 5-7.5
- Hardness: 1-12 NK°

Description: The base color of Hypselecara temporalis is yellowish-brown with a large characteristic black spot at the mid-section of the body, and a similar, but smaller spot at the caudal peduncle. The belly and the throat as well as the area around the gill cover and the eyes are bright red. The iris of the eye can vary from amber yellow to red. The juvenile fish have almost chocolate brown body, and they become more colorful as they grow. However their colors also depend on their mood.
Mature males have a typical nuchal hump on their forehead, and are larger than females. During courtship the male will display in front of the female, the pair swims side-by-side flaring their gills at each other, or the male nudge the female's flanks with his head. Sometimes lip-locking also occurs. After the courtship they will select and start to clean a flat, vertical surface such as stone plates or aquarium glass, which will be the spawning site. A fully-grown female can lay up to 1000 eggs, but the number of the eggs are usually between 400 and 800. As the female lays a batch of eggs the male will follow her, and fertilize them. This process can last for an hour. After the spawning the parents will guard and fan the eggs with their fins. The eggs will hatch after 2 days, and the fry will be moved to a large pit, previously dug in the substrate, where the parents will continue their care. After another 6 days the fry become free-swimming, and can be fed with brine shrimp nauplii. During the first couple of broods the parents often do a poor job caring their young or they may eat the eggs after spawning, but later this will change, and they become very good parents. Frequent water changes are necessary for Emerald Cichlids to develop their beautiful colors and stay healthy. The young fish become sexually mature when they reach about 12 cm in length.
