My betta has been acting normal, if not being a little shy. I've noticed just the past few days that his fins are eroding on the ends. I don't know how long this has been going on, as I had been on vacation for several weeks with a family friend caring for my aquatic creatures. I completed a water change on Thursday and added a dose of Seachem Prime directly to the tank today to supply some slime coat. I'm going to see if he improves, and I will post updates. I'm open to suggestions on course of action.
