Let’s be honest with you: there are tons of varieties of corydoras catfish.

 

We will take a look at only a few of them.

 

 

Julii Cory (Corydoras julii)

The Julii Cory is a much sort after corydoras species, though it tends to be relatively rare in stores because the region where the fish comes from is not heavily fished commercially.Therefore, it is common to see corydoras trilineatus incorrectly labeled as corydoras julii.Generally, cory julii should have small spots, be smaller in size, and with a more shorter head and a rounded nose.

 

Three Stripe Cory (Corydoras trilineatus)

The three stripe cory is another small adorable corydoras that is stunning almost as much as the Julii. In fact, the species is sometimes called, false julii cory, as well as leopard cory, leopard catfish, three lined catfish/cory, three strike cory or trilineatus cory.In case you don’t find a real julii cory in your local fish store (which are also more expensive), consider adding multiple three stripe corys in your aquarium for a reasonable price.Like the corydoras julii, the three stripe corys have spotted bodies and large black spot on the dorsal fin, but unlike a true julii, they don’t have finer sports on the head that are not connected.

 

Bronze Corydoras (Corydoras aeneus)

The bronze cory catfish (green corydoras, bronze catfish, light spot corydoras or wavy catfish) is a tropical freshwater fish of the armored catfish family.

It usually has a yellow or pink body, white belly and is blue-grey over the head and back. The fish is also yellow or pink and immaculate on the fins.

Bronze cories are found in quiet, shallow waters with soft bottoms that can sometimes be heavily polluted by a cloud of disturbed mud. But the fish also inhabit running waters.

 

Emerald Corydoras (Corydoras splendens)

The emerald green cory is a beautiful and interesting fish with a typically iridescent green body and pink highlights on the lower parts of the fish’s body. It is also called green cory or green catfish.The emerald green is a common fish in freshwater aquariums is the most popular of three fishes that are known as Brochis catfish, which are very similar to each other.Green corys are peaceful, undemanding and can be maintained under the same conditions as most corydoras species. Therefore, they are also not difficult to care for and great for beginners.They, however, need to be kept in a group of at least 6 individuals and are happiest in a group of 10 or more.

 

Panda Corydoras (Corydoras panda)

The panda cory comes from tributaries of larger rivers in central and South America and is a peaceful bottom dwelling scavengers. The fish is gold with black patterns covering the eyes, dorsal fin, and the base of the tail.The panda corys require a well-planted tank with plenty of hiding spaces that provide relief from the light. They also enjoy dimmer lighting and smooth and dark sand or fine gravel substrate, which makes sure the fish don’t easily damage their barbels.Like other corys, pandas enjoy being in numbers, so a small school of six should be the barest minimum.

 

Pygmy Corydoras (Corydoras pygmaeus)

If you are looking for a peaceful schooling cory with lots of personality for your nano tank, then the pygmy (dwarf) cory catfish is your best bet.These corydoras are small and rarely grow larger than 0.8 inches in length. Moreover, the species is particularly popular for shrimp tanks because of the peaceful nature.Dwarf corys have shimmering bodies that are peppered with black and green spotting. They do best when kept in a group of 6 or more.Your pygmy cory tank should have a smooth substrate, such as sand or fine gravel, as they tend to spend a lot of time at the base of the tank.

 

Peppered Corydoras (Corydoras paleatus)

The pepper catfish also called peppered cory, or the blue leopard corydoras is a peaceful cory species native to Uruguay and Brazil and is one of the more popular corydoras to keep.It’s body coloration is pale olive to tan with a green, iridescent sheen. The fish also has a network of dark green-black makings covering the body, and the dorsal fin has a dark-splotch on the first few rays.Pepper corys can be kept in a group of 5 or more individuals in a tank as small as 10 gallons. But to provide them with the best environment, it is recommended you maintain them in at least a 20-gallon long tank (80-100 liters).

 

Bandit Corydoras (Corydoras metae)

The bandit cory is an interesting, pretty little scaleless species that is very social and peaceful addition to a community tank.Corydoras metae is native to rivers and creeks in Colombia and is named after (the scientific name) one tributary of the Orinoco river, the Rio meta where the fish was first found.Even so, the more common name (bandit cory) is derived from the black band that runs from gill to gill going over the top of the fish’s head and covering both eyes like a mask.

 

Skunk Cory (Corydoras arcuatus)

The skunk cory is a peaceful hardy, armored catfish that will help keep the bottom of your fish tank clean while living socially with tank mates in a community aquarium.Most skunk corys sold in the trade today are commercially bred, but the wild form is native to the upper Amazon River basin in Brazil.Like other corys, the skunk is an armored catfish, which means instead of scales, the fish has overlapping bony plates and sharp spines on the fins.The fish body is creamy- white colored, sometimes showing an attractive yellow-gold sheen. Also, there is a black stripe that starts at the skunk’s mouth and runs through the eye then arches along the back.

 

Albino Corydoras

The albino cory catfish is a variety of corydoras that is developed in the aquarium fish trade from the darker bodied types.They are mostly pinkish-white in color with bright red eyes.Basically, there are two common variants: the albino aeneus cory developed from the bronze corydoras and albino paleatus made from the peppered cory.
