We recently purchased a female betta, (about 3 weeks ago), and the past couple of days she has been looking much fatter, and has also been acting differently. Today in particular, she has been highly energetic, FAR more than usual, swimming almost constantly, quickly, not resting...she seems to be more aggressive, staring at us and puffing up a lot, and has an almost insatiable appetite. She's like a different fish. She's like a pregnant woman ;)
I'm definitely a novice fish keeper, so if anyone could offer any suggestions as to what may be going on with her, I'd appreciate it. Should I be worried? Is she just full of eggs?
I tried to take photos of her, but she is in almost constant movement, so I was unable to get a great shot. Ugh! Just tried to upload photos but can't seem to get it done on a mobile.
Btw, if it is important, she is in a 10 gallon aquarium.
Thank you on advance! :)
