Web users were impressed by the fish after watching swim up a vertical wall and fighting to survive in the water stream<br />A 'miracle' fish has defied the odds and swam up against the water at a sewage discharge point.<br /><br />The video posted on Twitter shows the gold and orange-looking fish swimming up a ledge as water flows in a direction against it.<br />It wiggles and struggles for a second before making a big leap so that it is able to stay flat in the shallow water.<br /><br />The fish has been deemed "an incredible fighter" as Japanese web users commented on the clip.<br /><br />One said the fish was able to escape from a near-death situation and it is all thanks to its endeavour to stay alive.<br />Another one said the fish has taught him a lesson to "never give up" in a harsh environment.<br /><br />"If a fish can defy the odds, why not us? We should never give up!" he wrote.<br /><br />Some viewers pointed out that the fish might belong to a species similar to moss-eating fish.<br /><br />One said: "The reason why the fish could swim up against a wall is due to the 'suction cup' on its mouth, which allows it to attach to hard surface such as this."<br />Another commented: "It looks like a kind of tropical fish, but I don't remember the name of it."<br />But there were some that found it sad, predicting the fish would end up dying in the shallow water above.<br /><br />It is unclear where the clip was recorded, but it has amassed more 77,000 likes and has been retweeted more 20,000 times on Twitter.<br /><br />The fish stays at the edge as the stream was blocked by a filter barrier.<br />
