MBStevens Posted March 15, 2021 Share Posted March 15, 2021 Pretty positive I've got Columnaris in my tank killing off my fish one by one. Inevitably a new fish will get white columns on their side and die every 12 hours or so. I've been following the guide from fishlab.com recommending Furan-2 + Kanaplex. I'm getting discouraged as I'm on day 4 of 5 and still have a cherry barb on his way out. Somtimes it's one or two neon tetras at a time or a cherry barb. I was hoping to salvage most of my tank but I don't know if this will ever stop. Any encouragement for me? For whenever this is over....do I have to restart my tank? I hope not.

Colu Posted March 15, 2021 Share Posted March 15, 2021 (edited) Columnaris is a gram negative bacterial infection furan 2 kanaplex or maracyn2 are recommended treatment you just have to persevere with treatment it will get worse before it get better it can take two or three courses of treatment to fully cure columnaris Edited March 15, 2021 by Colu 1 Link to comment Share on other sites More sharing options...
