Hello all, my betta's fins aren't looking so good. The last day or so I noticed that a single fin was looking a little torn. Thinking it might heal itself up I didn't do anything, but started to keep a close eye on it.
Today when I went for his weekly water change his fins looked worse. Is this fin rot? I keep his water clean; I also do my best to keep bacteria out of his water, and I do weekly and monthly changes 25 -50 respectively. I can post using that guideline, but before I do that I figured these 3 pictures would suffice.
He's VERY active and getting a clear picture is next to impossible. Here are 3 I got. If anyone could tell me what this looks like and what the appropriate course of action would be I'd appreciate it.
