300Magnum 15 Report post Posted April 2 I have noticed my black calvus is sitting on the bottom and breathing hard. The rest of the fish look fine and the water parameters tested out all OK. I have noticed the edges of his gills look white. I have attached a photo below.....what can this be (gill flukes?). Share this post Link to post Share on other sites
Ageofaquariums 59 Report post Posted April 4 Double checking nitrite confirmed at 0ppm? Check temperature isnt too cool. Flat fish are very easy to inspect with a microscope while alive to confirm flukes. Without doing that its all guess work. Share this post Link to post Share on other sites
300Magnum 15 Report post Posted April 4 Ammonia and nitrite were both confirmed at 0. Nitrate on the other hand seemed high, although it is really hard to distinguish between 40ppm and 80ppm on the test kits. I ended up doing a 50% water change, and he is looking a LOT better. I will keep an eye on nitrate over the next few days and see how it goes. Temperature is within the correct range. Share this post Link to post Share on other sites
Ageofaquariums 59 Report post Posted April 4 Would not expect high nitrates to cause those symptoms, but water changes are never a bad idea IMHO..... well unless the problem is low temperature! Share this post Link to post Share on other sites
