I recently purchased a new betta, Bubbles the Destroyer™, and upon looking at him in a well-lit tank it became obvious that he has a case of fin rot.
I went out and picked up a box of Mardel's Trisulfa, and have been plopping a chopped in his tank for two days. Today I noticed that hidden inside the box's internal folding there is an expiration stamp for 2006!! I went back to the store and received a full refund, but I'm more concerned about poor Bubbles the Destroyer™.
Anyone know if I have doomed this poor guy? He seems as sassy as ever, but I am concerned.
