Peppered Catfish

The "Peppered Catfish”, “Corydoras paleatus" is also called "Peppered Cory," "Peppered Corydoras", and "Peppered Cory Cat".  This peaceful fish is a mostly harmless scavenger .  The only fish it eats are ones already dead, injured or too sick to swim away. It will eat the eggs of other types of fish and probably fry before they are free swimming.  It is an omnivore and will eat most types of food.  It is mostly a bottom feeding fish but it will eat at the surface at times.  This fish comes from the warmer parts of South America.
In an aquarium this fish will rarely get longer than two and a half inches (six centimetres) although in larger water bodies it has been known to get close to four inches (ten centimetres.)


 Origin

Corydoras paleatus is native to parts of Argentina, Brazil, Paraguay and Uruguay. It is found in the Lower Paraná River basin and coastal rivers in Uruguay and Brazil.

Length and Longevity

These fish can grow to about 10 cm (4 inches), but is usually less than this. They will supposedly live for 15 to 25 years.

Temperature

The Peppered Catfish is a ‘tropical’ fish although its low temperature tolerance is much better than most tropicals.  It does not seem to be able to take high temperatures well, and could be in trouble if the water temperature gets over thirty degrees C (eighty five degrees F.).   In a continuously heated house it can be kept without a heater, but I would not recommend it as a pond fish except in areas which never get very cold weather. 

Water 

The Peppered Catfish is not very fussy about its water chemistry.  I suggest a Ph of 7 (Neutral), definitely avoiding extremes of acidity or alkalinity, but it seems happy enough with a Ph range of 6.0 to 7.5.  The hardness of the water does not seem to matter to this versatile fish.  A clean tank is definitely better than a dirty one.
Make sure the water you use for your fish has had the Chlorine or Chloramine removed before it is added to the aquarium with your fish. 

The Peppered Catfish, like other scaleless fish, is sensitive to salt and none should be added.

Breathing

Like many Corydoras Catfish , the Peppered Catfish can swallow air and extract the oxygen with its intestines.  It is normal to occasionally see a Corydoras Catfish suddenly shoot to the surface where it presumably takes a quick gulp of air, and returning to the bottom.  If it does this a lot, it can be an indication of something wrong, such as the aquarium being short of Oxygen.
 
Companions

The Peppered Catfish can be kept without others of its kind, but does interact if given a chance.  Some people recommend six in a tank together, but this would only be practical in a larger tank.  There are many other fish which are suitable companions for this catfish .  Avoid extremely aggressive fish and very large ones, but most common aquarium fish should be all right.  This includes all the Tetras, nearly all the Barbs, Danios, White Clouds, peaceful dwarf cichlids , Angel Fish, Discus, Fighting Fish, Australian Rainbow Fish, other Corydoras Catfish and most loaches.
 
Uses

Apart from its interest and beauty in its own right the Peppered Catfish is often kept as a scavenger .  It is one of the fish that can be used as a scavenger in either tropical or cold water aquariums (As long as they are not too cold!) They will eat uneaten food on the bottom, but not fish waste.  Also, it is always important not to overfeed your fish, even with an efficient scavenger in the tank.  They are not specialized for eating algae and do not do the job of an algae eating fish like a Bristlenose catfish.
 
Breeding

Peppered Catfish are sometimes stimulated to spawn by a drop in temperature .  It has been reported that a simultaneous drop in barometric pressure helps.  It is a good idea to condition the potential breeders with meaty foods including things like Earthworms, Tubifex Worms or Daphnia.  One male and one female is the minimum requirement for breeding.  They are not communal breeders requiring a school to breed, but some people prefer two or three males for one female.
The female will clean surfaces such as a section of the aquarium glass or a leaf of a plant.  The male may rub against the female’s head, and she appears to drink his semen directly from his genital opening. 

She will lay her eggs into a ‘basket’ made with her fins, and attach the eggs to places she has cleaned.  After a while the process is repeated and continues until the female has laid all her eggs.  This can be over two hundred.
The eggs should hatch in about six days. Well-fed Peppered Catfish do not usually eat their babies.  At first the babies will eat mainly the protozoan organisms in the tank, but will soon be able to eat fry foods.
