Sometimes, the fish is damaged too hard to revive. Euthanizing is the most humane option. Don&#8217;t freeze it alive or flush it down the toilet, but add it to a container of water with clove oil. this is the most humane way for fish to die.<\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e6f4af1 elementor-widget elementor-widget-heading\" data-id=\"e6f4af1\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Why do Cory Catfish Die?<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-62f0b6f elementor-widget elementor-widget-text-editor\" data-id=\"62f0b6f\" 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>There are often multiple things that can cause the same symptoms.

In many cases, cory catfish suffer from severe stress causing death.<\/p><p>This stress can be caused by many things but it&#8217;s most likely one of the following:<\/p><ul><li><strong>Not being kept in groups<\/strong><\/li><\/ul><p>Cory catfish are group animals, and they should always be kept in a group of at least 6 individuals of the same species. this has a direct link with their tank size because you need at least a 20-gallon tank to house such a group.<\/p><p>When you keep less than 6 fish together, the cory catfish will not feel safe, which causes unnatural behavior and stress.<\/p><p>Read <a href=\"https:\/\/keepingcatfish.com\/how-many-cory-catfish\/\">how many cory catfish should be kept together<\/a> for more.<\/p><ul><li><strong>Wrong tank mates<\/strong><\/li><\/ul><p>Even though cory catfish are very peaceful fish that can live with most other fish, it can still be that they are being harmed by their tank mates. Some fish can outcompete cory catfish for food, or even attack the fish.\u00a0<\/p><p>This will mostly be the result of the two following points, otherwise, you have to separate your fish asap.<\/p><ul><li><strong>Tank size<\/strong><\/li><\/ul><p>The minimum tank size for cory catfish is 20 gallons. Some smaller species can be kept in 10-gallon tanks, but common types like albino cory catfish need 20 gallons to be housed in a group of 6.<\/p><ul><li><strong>Not enough\/bad natural cover<\/strong><\/li><\/ul><p>It&#8217;s a common occurrence to see cory catfish being kept in barely decorated tanks, without any live plants or natural structures.\u00a0<span style=\"font-style: inherit; font-weight: inherit;\">This however creates stress and might result in very shy behavior. It might seem contra-productive, but adding hiding places makes the fish less shy and more comfortable.<\/span><\/p><p>In contrast to fake plants, add live plants. And in contrast to the fancy sponge bob house, you bought in the pet store, add a piece of driftwood or a stone.\u00a0<\/p><p>Lastly, pay attention to <a href=\"https:\/\/keepingcatfish.com\/the-best-substrate-for-cory-catfish\/\">the kind of gravel<\/a> you are using. The best choice is a dark-colored substrate or sand. Bright colored gravel kinds like in the picture below reflect too much light color and stress these 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-5ec0367 elementor-widget elementor-widget-image\" data-id=\"5ec0367\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"570\" src=\"https:\/\/keepingcatfish.com\/wp-content\/uploads\/2022\/01\/Schermafbeelding-2022-01-28-om-19.51.31-1024x570.jpg\" class=\"attachment-large size-large wp-image-3228\" alt=\"\" srcset=\"https:\/\/keepingcatfish.com\/wp-content\/uploads\/2022\/01\/Schermafbeelding-2022-01-28-om-19.51.31-1024x570.jpg 1024w, https:\/\/keepingcatfish.com\/wp-content\/uploads\/2022\/01\/Schermafbeelding-2022-01-28-om-19.51.31-300x167.jpg 300w, https:\/\/keepingcatfish.com\/wp-content\/uploads\/2022\/01\/Schermafbeelding-2022-01-28-om-19.51.31-768x428.jpg 768w, https:\/\/keepingcatfish.com\/wp-content\/uploads\/2022\/01\/Schermafbeelding-2022-01-28-om-19.51.31-1536x855.jpg 1536w, https:\/\/keepingcatfish.com\/wp-content\/uploads\/2022\/01\/Schermafbeelding-2022-01-28-om-19.51.31.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Blue gravel stresses these fish and is not a good choice.<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4ae0862 elementor-widget elementor-widget-heading\" data-id=\"4ae0862\" 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\">Shocks<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c2d2661 elementor-widget elementor-widget-text-editor\" data-id=\"c2d2661\" 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>It&#8217;s not uncommon for cory catfish to go in a &#8220;shock&#8221; mode. This is most likely because of one of the following two reasons:<\/p><ul><li><strong>Low amount of other fish<\/strong><\/li><\/ul><p>In the pet store, fish are often crowded in an overstocked tank. Cory catfish will see a lot of movement. When they get added to your tank without any tankmates, they might get shocked or severely stressed. Adding other active tank mates will help this and reduce the stress.<\/p><ul><li><strong>Water parameters<\/strong><\/li><\/ul><p>Before adding your fish to your own tank, it&#8217;s important to climate them first. If you want to be sure, ask the pet store what the water conditions are like, a good store will know this.<\/p><p>Depending on how big the difference is between you and where the fish comes from, the amount of acclimatization varies.<\/p><p>I recommend setting up a separate tub and putting the cory catfish in this. Then add an air tube with a knot in it, so the water from your tank gradually drips in.\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-1699a8c elementor-widget elementor-widget-heading\" data-id=\"1699a8c\" 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\">Overstocking<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8d95510 elementor-widget elementor-widget-text-editor\" data-id=\"8d95510\" 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>Overstocking is a severe problem when keeping catfish.

Yep, that&#8217;s only one piece I read online. As stated multiple times in this blog post, many species need 20 gallons to be healthy and happy.<\/p><p>And even then, you should always do your research and make sure you aren&#8217;t overstocking your tank.
