Probably because I am back to regular, weekly 25% water changes. It turns out that both green and black algae do go away if the water is changed regularly, just \u00a0like all the books say (or the algae eater did its \u00a0thing?)<\/p>\n<figure id=\"attachment_685\" aria-describedby=\"caption-attachment-685\" style=\"width: 604px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/harsmann.com\/blog\/wp-content\/uploads\/2016\/05\/20160515-Severums.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-685\" src=\"http:\/\/harsmann.com\/blog\/wp-content\/uploads\/2016\/05\/20160515-Severums-1024x675.jpg\" alt=\"Two young severums with different patterns.\" width=\"604\" height=\"398\" srcset=\"https:\/\/harsmann.com\/site\/wp-content\/uploads\/2016\/05\/20160515-Severums-1024x675.jpg 1024w, https:\/\/harsmann.com\/site\/wp-content\/uploads\/2016\/05\/20160515-Severums-300x198.jpg 300w, https:\/\/harsmann.com\/site\/wp-content\/uploads\/2016\/05\/20160515-Severums-768x506.jpg 768w\" sizes=\"auto, (max-width: 604px) 100vw, 604px\" \/><\/a><figcaption id=\"caption-attachment-685\" class=\"wp-caption-text\">Two young severums with different patterns.<\/figcaption><\/figure>\n<h3>Concerns about Stocking Compatibility<\/h3>\n<p>One thing I am watching out for is how well the severums will mix with the other fish already in the tank. As <a href=\"http:\/\/harsmann.com\/site\/2016\/03\/new-fish-severums\/\">previously described<\/a>, my aquarium has been\u00a0a community tank so far and adding a handful of large, somewhat temperamental fish could well change it into something else.<\/p>\n<p>Among my initial concerns:<\/p>\n<ul>\n<li>Will the severums and the corydoras get along<\/li>\n<li>Will the rummy-nose tetras get eaten?<\/li>\n<li>How will the different cichlid species react to each other?<\/li>\n<li>Wil the severums accept the gouramis<\/li>\n<\/ul>\n<p>Here is how things are going so far. In <em>my<\/em> tank. These are living creatures and just because a thing &#8211; good or bad &#8211; happened in my tank, doesn&#8217;t mean it will happen anywhere else, , all things being equal). I lost some fish, platies and cupidos, but none of them were doing\u00a0well\u00a0before the severums were added, so that doesn&#8217;t have to mean anything.<\/p>\n<p><strong>Severums and Severums<\/strong><\/p>\n<p>This is the conspecific aggression.\u00a0I see that already, with the oldest looking fish generally being the boss, and one of the smaller ones looking increasingly ragged. They chase each other sometimes,but behave during meals.<\/p>\n<p><strong>Severums and Corydoras<\/strong><\/p>\n<p>The cories are small bottom feeders who may come into the severums&#8217; area of interest. So far there are no problems. Perhaps because the cories are most active at night, perhaps because they are already cautious because of the cupidos and the algae eater.<\/p>\n<p><strong>Severums and Rummy-nose tetra<\/strong><\/p>\n<p>The severums are still too small for the rummy-noses to fit into their mouths. However, I notice that the rummy-noses are less active lately, spending most of the time in one corner of the tank, together with other fish too. That may also be due to the tank getting hit by direct sunlight at the moment and the fish hiding from that.<\/p>\n<p><strong>Platies and Severums<\/strong><\/p>\n<p>Severums doesn&#8217;t seem to care about them. The platies aren&#8217;t doing too well though and I have lost 3 or 4 since the severums moved in, but that is probably \u00a0due to \u00a0other factors, like the\u00a0water temperature. I have not had a lot of success with platies in this tank.<\/p>\n<p><strong>Knife Fish and Severums<\/strong><\/p>\n<p>So far they ignore each other. The knife is a large fish but also hides most of the day (except when feeding) so there isn&#8217;t much to fight about. All peaceful so far.<\/p>\n<p><strong>Cupidos and Severums<\/strong><\/p>\n<p>Some aggression observed and I speculate if the weaker-looking cupidos are getting worse. Maybe they are and maybe this has been going on over long time, only i just see it now. Maybe it is changes to the food and maybe the weekly changes of water that isn&#8217;t ideal to the fish either.<\/p>\n<figure id=\"attachment_683\" aria-describedby=\"caption-attachment-683\" style=\"width: 604px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/harsmann.com\/blog\/wp-content\/uploads\/2016\/05\/20160515-Cupido.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-683\" src=\"http:\/\/harsmann.com\/blog\/wp-content\/uploads\/2016\/05\/20160515-Cupido-1024x683.jpg\" alt=\"Biotodoma cupido\" width=\"604\" height=\"403\" srcset=\"https:\/\/harsmann.com\/site\/wp-content\/uploads\/2016\/05\/20160515-Cupido-1024x683.jpg 1024w, https:\/\/harsmann.com\/site\/wp-content\/uploads\/2016\/05\/20160515-Cupido-300x200.jpg 300w, https:\/\/harsmann.com\/site\/wp-content\/uploads\/2016\/05\/20160515-Cupido-768x512.jpg 768w\" sizes=\"auto, (max-width: 604px) 100vw, 604px\" \/><\/a><figcaption id=\"caption-attachment-683\" class=\"wp-caption-text\">Biotodoma cupido<\/figcaption><\/figure>\n<p>On Apr 19 \u00a0one of the Cupids died and another went yesterday, but no obvious explanation why, except that it was the worst looking one(s).
