I'm really worried about the fins on my betta fish. Do they look normal? I've been reading about fin rot, shredded fins, and all sorts of things trying to figure this out. This is my first ever fish. I'm really trying to do everything right, but it seems like every website I visit says something different about the best environment for Betta Fish. He's in a 2.5 gallon tank with a filter, heater, and thermometer. The water temperature is 75 degrees Fahrenheit. The plants are silk and are very soft. He's been in this particular tank for about 2 weeks. I've had him since Easter, but he was in only a half gallon to start with. I just got him a bigger one. And yes, I know he needs a bigger tank than 2.5 gallons. He was a gift and I'll be getting him one when I can. If you can please advise me on what a normal betta tail is suppose to look like I'd appreciate it. I'm really worried about the little gu y y.
