Hey Guys, new to the forum but not fish. I've had fresh and brackish tanks for years, however I'm new to Betta's. My Wife got a Betta from Petco, it was labeled as a "Betta Baby" so not even sure exactly which one it's supposed to be. She got it in February, and while it's gotten bigger, mainly longer it (to me) doesn't seem to be developing right. It's back fins are barely noticeable and the front of his body seems to have gotten bigger but not the back. He also seems to swim a little weird, im sure thanks the the lack of real rear fins. Were feeding him flakes which we have to grind up to almost dust so he can eat them, I've also tried really mashed up blood worms, lately it seems he doesn't have much of an appetite. The tank is a 2.5g betta bow, heated and filtered, ph right around neutral and temp is usually around 74-76. Any ideas are much appreciated.
