The gill spot diamondfish ( Enneacanthus gloriosus ) belongs to the sunfish (Centrarchidae).
distribution
Its distribution area is in the east of the USA , from New York to the south of Florida . It prefers heavily overgrown, standing or calm flowing water.
Physique and coloring
The animals, which can grow up to 10 centimeters long, have a high-backed, laterally compressed, typical perch shape. They are light or olive brown with 5 to 8 dark, vertical bands on the flanks. Older fish do not have these stripes. The head, sides and fins of the animals are covered by numerous small blue dots.
Reproduction
Like the closely related diamond bass, the gill spot diamond bass spawns in a small hollow near aquatic plants. When spawning, the female wags her tail so that the fertilized eggs are washed into the plants. Up to 500 eggs are laid. The male then takes over the guarding of the brood. It protects the eggs from predators and repeatedly fills them with fresh oxygen so that the eggs can develop better. The young hatch after two to three days. If the yolk sac of the larvae is used up, the brood care instinct of the animals disappears.
Aquaristics
The enneacanthus gloriosus is in the hunting in a so-called cold-water aquarium maintained. The water temperature should be between 10 and 22 degrees Celsius. The pH at which these fish feel comfortable is 7.0 to 7.5. The fish are very sensitive to fluctuations in the pH value. Therefore, the carer must be careful when moving or changing the water. The aquarium should be planted and contain stones and roots in addition to a soft substrate. The animals use this to demarcate areas in the basin and to hide. However, the gill spot diamondfish are considered to be demanding in terms of feeding. He usually does not accept dry food ; he must be provided with live food .
