I think my betta is about done for. I've only had him for 4 months or so, but I think he was fairly old already. If not, he wasn't exactly in top shape. Besides the big lump in front of his tail that you can see in the picture, when I got him he had a big spot over one pupil the color of his scales, and always seemed to have a bit of a hard time seeing on that side. Other than that, he's always looked and acted pretty healthy and was a good eater, even though he would miss pretty often when he made a grab at his food. Well, now that spot has completely covered his left pupil, and is spreading fairly quickly on his other one. I've noticed for the last few days that he's had a harder time finding his food, even right in front of his face, so I have a feeling it won't be long before I'll have to put him down to avoid having him starve to death. It sucks, but I don't think there's much else to be done about it.
