I've had my male betta, Cliff, for about 7 months now and during all of that time, he's been a very social, seemingly healthy fellow. Normally, Cliff enthusiastically greets anyone who approaches the tank (even the cat) and he ALWAYS has a voracious appetite. Indeed, I suspect he fancies himself a "micro-Great White shark" because he will literally breach the surface to get at a pellet balanced on my finger (or bite any finger offered up as a sacrifice).
Recently he started spitting out his food or refusing it altogether and hiding at the back of the tank amongst the fronds of a fake plant. This has been going on for almost two weeks. He will still come out to eyeball you if you approach the tank, but he loses interest quickly and goes back to hiding behind the plant. Sometimes, if you get close to the tank to get a good look, he will come out and flare at you. He's never been big on flaring, so it's odd.
Anyway, I am very concerned about the change in behavior and the fact that he's eaten almost nothing for nearly two weeks.
Please help me. Cliff is a sweet little dude and I want him to live a long and happy life (a long life in betta terms anyway). Thank you very much!
