most obvious sign that your betta fish has popeye, one or both eyes can be affected.<\/p>\n\n\n\n<p>If you notice that your betta&#8217;s eyes are bulging, you should treat it for popeye as soon as possible.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"htoc-white-ring-around-eyes\">White Ring Around Eyes<\/h3>\n\n\n\n<p>If you notice a white ring or splotches around your betta fish\u2019s eye

this, as it seems like too much hassle.<\/p>\n\n\n\n<p>If you don&#8217;t quarantine new tank mates, you can very easily end up with a tank full of infected fish that you need to treat.<\/p>\n\n\n\n<p><a href=\"https:\/\/aquaristgeek.com\/ich-on-fish-freshwater\/\" target=\"_blank\" rel=\"noopener\" data-lasso-id=\"1161\">Ich<\/a> in particular can be a nightmare to get rid of!<\/p>\n\n\n\n<p>Quarantine new fish for 4-6 weeks, this gives you time to spot and treat any disease they may be carrying, before adding them to your main tank.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"htoc-avoid-overstocking-your-tank\">Avoid Overstocking Your Tank<\/h3>\n\n\n\n<p>Overstocking your tank increases the amount of waste (poop, rotting food etc) in your tank, putting strain on the<a href=\"https:\/\/aquaristgeek.com\/aquarium-nitrogen-cycle\/\" target=\"_blank\" rel=\"noopener\" data-lasso-id=\"1162\"> nitrogen cycle<\/a>.<\/p>\n\n\n\n<p>If there is too much waste in your tank, the nitrifying bacteria will not be able to keep the ammonia, nitrites, and nitrates at safe levels for your fish.<\/p>\n\n\n\n<p>This will stress your fish, weaken their immune system, and leave them more open to disease and infections.<\/p>\n\n\n\n<p>You&#8217;ll need to upgrade to a larger tank or re-home some of the fish to solve this.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"htoc-clean-your-filter\">Clean Your Filter<\/h3>\n\n\n\n<p>Filters are a great breeding ground for beneficial bacteria, but they eventually get clogged up with sludge and debris.<\/p>\n\n\n\n<p>Every month or so, in a separate container or large ziplock bag, rinse your filter media in tank water.<\/p>\n\n\n\n<p class=\"has-text-align-center has-background\" style=\"background-color:#7cdfd4\"><strong>Do not use tap water to clean your filter media. <\/strong><br><strong>Tap water contains chlorine or chloramine that will kill the beneficial bacteria you&#8217;ve colonized.<\/strong><\/p>\n\n\n\n<p><strong>Use the dirty filter water to water your plants, they&#8217;ll love it&#8230;you can&#8217;t buy better fertilizer than this!<\/strong><\/p>\n\n\n\n<p>If the filter media is beyond rinsing and needs replacing, do this gradually and replace around 30% of the filter media at a time, over the course of several weeks.<\/p>\n\n\n\n<p>This is so that the beneficial bacteria have time to colonize the new filter media.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"

don&#8217;t die from popeye itself, as it is caused by an underlying issue or trauma to the eye.<\/p>\n\n\n\n<p>Sometimes a betta fish will lose an eye if it is badly damaged, but it can survive fine with only one eye.<\/p>\n\n\n\n<p>If betta popeye is caused by an underlying issue, such as dirty tank water, disease, or infection, it can die from that if not treated.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"htoc-is-popeye-contagious\">Is Popeye Contagious?<\/h3>\n\n\n\n<p>Popeye itself isn&#8217;t contagious, but the underlying issue that has caused it may be contagious.<\/p>\n\n\n\n<p>If your betta has one swollen eye, chances are it&#8217;s caused by trauma, therefore it&#8217;s not contagious.<\/p>\n\n\n\n<p>If your betta has two swollen eyes, it is
