Hi^^ i thought about that as well, he may or may not have adapted but after shrimps i put in his tank eat his fins away which made the issue more visible, he had an open sore where his skin has start to rot away which may have caused SBD in him.Hi Sprinkle, it took me a few minutes to read the whole thread, I'm sorry about your Betta, I must say that maybe he never adapted, I think you just got good things, it's always exciting to receive something new for our tanks! Good luck with those gouramis, my LFS has some available and I've seen that those things are really small.
