Cory Catfish are a species that shows <a href=\"https:\/\/en.wikipedia.org\/wiki\/Sexual_dimorphism\">sexual dimorphism<\/a>. This means that males and females show visible differences in their appearance. But what are the differences between male and female Cory Catfish?<\/p><p><strong>When fully grown, females will be bigger and fatter than females. There are also some differences in the finage between male and females. Overall, The pelvic, ventral and anal fins of females tend to be bigger and more rounded.\u00a0 With some species like C. elegans ssp., males may be more colorful than females<\/strong>.\u00a0<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-31d05e8 elementor-widget elementor-widget-heading\" data-id=\"31d05e8\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Letting your Corydoras grow up to their full size<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b58343a elementor-widget elementor-widget-text-editor\" data-id=\"b58343a\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Before even trying to tell the sex of Cory Catfish, it&#8217;s important to wait until they have matured. <a href=\"https:\/\/keepingcatfish.com\/raising-cory-catfish-fry\/\">Cory catfish fry<\/a> \/ young fish can&#8217;t be sexed.<\/p><p>Cory Catfish are fully grown after 9-12 months. At this time, it will be way easier to see the difference between a male and a female. Only then the difference in size and fins will be visible.<\/p><p>On top of that, they will only be able to breed at this age. Trying to tell the sex of Corydoras apart at this age is thus not useful.<\/p><p>Cory Catfish are often sold when they are still young fish not yet matured. So, when you are thinking about getting Cory Catfish, especially if you want to breed them, get at least a group of 6 fish. This is necessary anyway since <a href=\"https:\/\/keepingcatfish.com\/how-many-cory-catfish\/\">Cory Catfish have to be kept in groups<\/a>. With six fish, you have a chance of 98,4% on at least one male\/one female.<\/p><p>Another reason to pick up a good amount of Cory Catfish is that you have something to compare to. When you for example have four male Cory Catfish. You might think that the slightly bigger or fatter is a female. It&#8217;s only normal that even of the same sex, fish show some differences. If you have a big group, there&#8217;s a bigger chance you have at least one real female easily distinguishable to whom you can compare the other fish.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-730aa5e elementor-widget elementor-widget-heading\" data-id=\"730aa5e\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Size differences male vs. female<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4ac7a14 elementor-widget elementor-widget-text-editor\" data-id=\"4ac7a14\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>The most described way of telling males and females apart is telling the size difference.\u00a0<\/p><p>On average, but highly depending on the species, males are about 0,2 inches (0,5cm) smaller than females, measured from head to tail. If you want to know more about exact Cory Catfish sizes, read <a href=\"https:\/\/keepingcatfish.com\/cory-catfish-size\/\">How big do Cory Catfish get?.<\/a><\/p><p>As stated above, this is very different per species.

The easiest way to see this is by looking from above.<\/p><p>Another way is but looking at the fins of the Corydoras. Males tend to have narrower and more pointed ventrals and pectoral fins, but smaller anal fins.
