Long story short, my betta Phoebe has been sick with just about everything for as long as I've had her . She is now septic, and the infection is now at the base of her petctoral fin, extrodinarily close to her gills. I'm making one last stab at healing her, and if that doesn't work, or should she get in a worse condition, I'm going to have to put her down humanely. I know clove oil will do the trick, and I'll get some soon, but I would like to know how to go about doing this correctly. Thanks
