RyukinFan 13 Posted March 24, 2020 Good Evening Everyone, Apologies I have not posted for quite some time, but I really am desperate for some help please. I purchased two new Ryukin recently, one of the fish almost immediately started showing signs of columnaris, I contacted the dealer and was advised to use Acriflavine and salt. We have been in regular contact regarding the treatment and have slowly raised the dosage for the fish, they were in a 360 litre tank, however, I have since moved them into a 40 litre tub to enable daily water changes. I have now been advised to raise the dosage to 5kg salt per 220 gallon and increase acriflavine dosage by 25% to 2ml per 10 gallon. I am changing the water daily. The fish are still swimming freely and have an appetite, however, their mouths are perishing. I am now becoming increasingly worried that this strain is resistant to acriflavine and am struggling to obtain other medications listed on this site. Would it perhaps be worth bathing in methylene blue instead? Any help would be greatly appreciated. Thank you. 0 Quote Share this post Link to post Share on other sites
RyukinFan 13 Posted March 26, 2020 Hi all, Just an update, the fish appear to be showing less interest in food now, getting quite desperate if anyone has any ideas? Thank you. 0 Quote Share this post Link to post Share on other sites
