Corydoras julii

July catfish ( Corydoras julii )

The July catfish ( Corydoras julii ), a catfish of the whitetail catfish ( Corydoras trilineatus ) is similar looks. In July armored catfish is not about Leopard armored catfish Corydoras leopardus, with whom he is also confused often. Corydoras julii only have come from the same genus as Corydoras trilineatus, but have developed in parallel to these.

Occurrence

The July catfish in certain tributaries of the Amazon is home, in South America: Brazil; Maranhão, feed the Rio Parnaíba near the Alto Parnaíba (09 ° 08 'S, 45 ° 56'W ).

Other Locations: Brazil, rivers in the state of Pará.

Features

The male is up to 5 cm and the females up to 6 cm in size, the achievable age is 5 to 10 years. How noticeable when viewing images, the Corydoras julii is the much finer dotted species. However, C. trilineatus is much more robust than C. julii.

Fins formula: Dorsal 1/7, Anal seventh

Hunting and

For entertainment in the aquarium, it is important that it is kept in a shoal of at least 5 animals and a lot of hiding places in the aquarium are available. Suitable values ​​are a water temperature of 22 to 26 ° C and a pH value of 6.0 to 7.5. The water hardness should have d at a KH- value of 2 to 5 ° and a GH value from 2 to 15 °. The aquarium should be at least 80 liters.

Nutrition

The July catfish is omnivorous ( omnivorous ) and feeds on algae, detritus, small animals and plant parts. Live food ( brine shrimp, bloodworms, daphnia, tubifex ), frozen food and dry food ( pellets, flake food ): In the aquarium fish feed is the following.

Propagation

In the wild, the armored catfish perform after the rainy season when the water has warmed up again, their species-typical mating behavior, since a lot of suspended solids and thus prey animals are in the water after the rainy season. The water is much softer through the rain, so a conductance of about 60 ĩS should be selected for breeding.

Most likely to succeed in the proliferation in the aquarium after the rainy season, modeled on one to three -day cooling water by two to three degrees and rich feeding, with subsequent reheating. Best used breeding groups with a ratio of two males to one female together; the animals mate in nature in larger groups. The animals make a special mating behavior in which the male circles the female and strong twitches, the female cleans certain areas of the aquarium ( discs and leaf undersides ) around it then staple the approximately 100 eggs, which are then fertilized the male. The eggs should be separated from the mature animals. At 26 to 28 ° C, the larvae need to hatch about 5 days. The larvae are very small and almost transparent. Two to three days after hatching, when the yolk sac is depleted, the larvae can be fed with newly hatched Artemia. Later finest flake food can be given.

The offspring of the C. julii is extremely difficult because the animals are strong and healthy enough only for very specific water values.
