So not yesterday but the day before, I noticed that Mojo's tail & upper fin were looking a bit ragged. He was my first betta (just purchased about 2 months ago) so when we set up his tank accessories, they probably weren't the "best". We still had 2 plastic plants in there. They weren't terribly rough, but for one with such a fluttery tail, I could see how they might damage him a bit -- especially since he either sleeps against his plants, in his cave, or literally on his side on the gravel surface. So in order to soften up his environment, we went out & got silk plants to replace the plastic ones, the polished rock gravel since the exterior is more smooth, & also a bigger cave so as to reduce/eliminate any possible scraping that would occur. I did a 100% water change for him when rearranging his tank & even added some AQ salt just to be safe. Today, his fins are looking far more ragged and there is even a slightly different color around the edges. Does this look like possible tail biting (which I have never seen him do) or is this the starting stages of fin rot? What should my next steps be? He doesn't seem as playful as normal, but he is not exactly lethargic either....Here are 2 pics just taken a few moments ago. The first really shows the ragged-ness of his fin/tail and the second better shows the slight discoloration. I just don't know what to do!
