So, recently my Betta's health has gone downhill. He doesn't seem to be eating anything I give him, and just sits around in various corners of the tank all day. (It's a five gallon tank.) The tank is heated between 75 and 80 degrees and he also has a filter.
He has one white spot that's on one of his fins. He seems to scratch across the gravel a lot. He leans up against anything and everything, I've even caught him laying on top of one of the plastic plants.
He's gotten sick before, and at that time I had given him some Lifeguard tablets that really perked him up and he went back to his old active self. I tried them again this time since they were so effective last time and they didn't work. I currently have him on a Melafix treatment and that doesn't seem to be doing much either.
I noticed when I began Melafix that there were lots of stringy lines of poop hanging around everywhere that I've never seen before in my year of having him.
Any ideas on what I can do or what it is? I fear he doesn't have much time.
