I have a relatively young betta, about 9 months old (he was very small when we got him) and he cannot
eat. He seems top heavy, leaning to the side slightly as he swims. He seems desperate to eat, but he appears to not be able to see the food although he's right under it. He leaps at it, may get it in his mouth after several attempts and then spits it out.
This is the same food he's been eating since we've had him and he's always been a great eater. It's almost as if he has something blocking his mouth.
No bulgy eyes, still has good color, etc.
I'm afraid he's starving to death (this has been going on for about four days now).
Any ideas what could be going on?
