What Is Corydoras?
 

- Corys are called armoured cat fish who only live in the whole South America. They are very lovely, peaceful, and coward a little bit. They love to stay in the shadow area under the bogwood, rock, and stone. There are more than 300 species of Corydoras in the South America. The three corys, aeneus, albino aeneus, and paleatus, are mainly seen in the United States.

Paradise of Cory in Japan and Germany
  - Compared to the United States, corys are very popular among the Japanese fish lovers. Although there exists more than 300 species of Corydoras, 100 out of 300 species are sold in Japanese fish shops. Some people are willing to pay a lot of money to get a beautiful and precious corys. - Some Germany discovered new species of Corydoras and discribe them in the books.

What is the Beautiful corys?
 

- The fundamental condition of the beautiful corys is healthy. In addition, the Japanese aquarists want to buy the good corys, whose bodies have a beautiful pattern such as lines and dots. The good corys tend to have a long barbel, although there are two types of berbel, long-snoted and short-snoted.

- What is the beautiful pattern? The left picture shows Corydoras arcuatus who have two black lines from the berbel to the tail displaying an arch. If these two lines are close to each other, the cory lovers regard him as rare. Some Japanese cory lovers buy this cory spending a lot. Unfortunately, the right picture is the normal arcuatus. The fascination of cory is so profound...

How Lovely!
  - Corys are very lovely fish. I would like to write down as many lovely behaviors as possible.
 
  • They do wink.
  • They often stay under the shadow around plants and rocks.
  • They love to eat worms satisfactorily.
  • Schooling: if one moves, everyone moves.
  • They swallow a piece of sand and emit it from their gills.
  • They swim to the the surface of water to get an air so fast.
  • Peaceful
  • Barbel
  • Coward
Your corys are healthy? - how to distinguish healthy corys -
 

- Corys basically don't often move back and forth (depend on species) but just stay under a wood and stone except in the meal time. The healthy corys love to eat most foods such as artificial feed(flak and tablet) and living, dried and frozen worms (Some corys, especially long-snoted corys don't eat flake). When they have such feeds, they move and try to find them rigorously. When they are not fine, they don't move and keep quiet even if they are given feeds. The unhealthy cory sometimes folds up its fins. The unhealthy corys also swim in the upper level of a water tank without any purpose. That will be the one of signs if they are sick.

Popular Corydoras
  - There are so many species of corys, which are discovered and undiscovered, but I would like to introduce popular corys. If you would like to see the picture, just click the name (Sorry that some sps don't have pictures).
 
  • Corydoras aeneus - just a regular cory.
  • Corydoras albino aeneus - the albino type of aeneus.
  • Corydoras paleatus - it's sometimes called "spotted cory" or "peppered cory."
  • Corydoras sterbai - big and timid cory. The body pattern has many white spots on the black colored base with orange colored fin. To the contrary, C. haraldcschultzi have many plack spots in the white colored base.
  • Corydoras panda - as its name tells, the body pattern looks like Giant Panda in China.
  • Corydoras adolfoi - it is one of most beautiful corys. The symbol is the light orange color on the head and black colored band on the back.
  • Corydoras julii - similar to sterbai a little bit.
  • COrydoras trilineatus - almost same as julii, but the body pattern is different a little.
  • Corydoras delphax - the long nose type (see below "long nose vs.. short nose"). Many tiny spots are on its body.
  • Corydoras elegans - there are many different types of elegance species. (see "Corydoras elegans")
  • Corydoras arcuatus - the common name is skunk from two black lines.
  • Corydoras schwartzi - there are two black straight lines on the body.
  • Corydoras parallelus - the common name is correai. It is one of the most expensive corys. The body pattern is silimar to schwartzi.
Corydoras aeneus
 

- This cory lives in the all over the area in the South America. So, its shape and color is different in each area even though each name is aeneus. As long as I know, the color of this cory is normally bronzed pink such as the left picture, but there are blue, green, and orange colored type. The cory lovers like these minor differences of this cory.

Corydoras elegance
 

- C.elegans also lives in most area of the South America. Both figure and color of this cory are different in each area as those of aeneus corys are. C.elegans has the characteristic shape. There are many kinds of corys which has this shape (attension to berbel and mouth in the left picture!). Most corys love to stay under the wood and rock, but corys in the elegance group tends to stay on the wood and rock.

- The left picture shows Corydoras nijsseni, but most elegance species look like this with different body patterns.
