Hey Lion ! That puffer was the same Black puffer who got sick last month. After I tried all the different methods, I gave up, and returned him to my LFS. And they treated him with dips and MELAFIX and PIMAFIX. So I got rid of most of my overstocked fish and got back my puffer. So when I was acclimating him, and getting ready to pour him into the bucket to start the driping, he slipped and fell on the floor, for maybe the longest 20 seconds in my life. But after all the drama, he's in my tank,swimming fine, and eating like a horse !!
