Corydoras paleatus

Corydoras paleatus
Peppered Corycat
Corydoras paleatus is a species of catfish (order Siluriformes) of the family Callichthyidae. Its common names include peppered cat, pepper cory. It originates from the lower Paraná River basin and coastal rivers in Uruguay and Brazil. This fish species reaches about 6 centimetres. The male is smaller than the female and in proportion to body length, the dorsal fin and pectoral fins are longer on the male than the female.
Corydoras paleatus is found in the amazon basin, and feeds on worms, crustaceans, insects, and plant matter.
C. paleatus has been known to produce sound; it does this by abduction of its pectoral fins. This is used by males during courtship and intrapersonal communication, and by both sexes and juveniles when distressed.
In reproduction, males do not behave aggressively toward each other, nor do they monopolize mating areas or females. The T-position is involved in courtship, as with many other Corydoras species.
It is a very good choice for the community aquarium, as it is a hardy, good looking, and peaceful fish. They can be successfully kept with other small, peaceful aquarium fish like livebearers, danios and tetras. It is sometimes seen in the shops as an albino form, although this is similar to other albino corys 
These fish have sensitive barbels and one should have the proper substrate for them. To keep their barbels (whiskers) in the best condition one requires the fine gravel that looks like coarse salt. 
These fish prefer a planted tank with temperatures around 22 to 28 degrees Celsius although they can take lower temperatures than this. Their high temperature tolerance seems poor and 30 ºC is the highest safe temperature. They like to nibble on the algae that grows on floating plants, but are not a specialized algae eating catfish. The lighting must not be too bright and you need to set up hiding places, such as bogwood (also known as mopani wood) for them as they like to hide from the light during certain parts of the day. Also provide heavily planted areas, where the light is minimized as they like darker areas due to their bottom feeding nature.
Feed them on a mixed diet of sinking pellets, algae wafers, frozen and live food, such as bloodworm or daphnia. They may also occasionally enjoy a bit of blanched spinach, which you can attach to plants with a peg or the side of the glass with special magnetic clips. You may also see them dart quickly to the top of the tank, this is natural because they can use atmospheric oxygen to supplement what their gills extract from the water. 

受精卵经过96小时左右便可孵化出幼鱼,幼鱼再经过24小时左右便可游动,摄食、这时应喂以“灰水”。 幼鱼约需9个月达性成熟,一年可繁殖多次。如果正确饲养,寿命可长达五年。
