Hello, everyone! As some of you may know, I have a lovely new (and young and small) little green betta named Caravaggio. Maybe day or so ago, he stopped spreading his fins out, and I'm wondering whether or not his fins are clamped. I've put in some pictures of him before, and now. The before pictures are much higher quality. I'm sorry I couldn't get nice pictures right now but I'm in a dorm room so good light is hard to find.
He's in a 1 gallon jar that's been about 75 degrees for the past day and that has 50-75% water changes every other day. On Monday he'll be moving to a 3 gallon filtered tank with a lovely new heater that will keep him comfortable. Last Sunday, he undertook a 5 hour car ride but he seemed to take it extremely well.
He still swims around actively, but perhaps not with quite so much energy as a few days ago. I've had him for about a week and a half. Last night I observed him simply floating up toward the top of the tank (horizontal, belly-down) before starting to swim again. I don't know if that's important or not.
Before pictures (taken last Saturday):
Pictures I just took: His color is still dark green. He looks blue in some of the pictures because I wanted lots of light on him, and in some light he looks blue. I'm not sure whether or not he looks blue when stressed as well, but it's possible.
Is he sick? What should I do? : (
