I've found our betta (male) fish stuck in the filter.
(I saw that he wasn't that fast in the last few days anymore, but on the other hand he's about 3+ years old, so I thought he might have gotten a little bit slowly with the time. He also seemed to have trouble catching his food with the filter moving it around all the time.)
Today when trying to feed him, I found him stuck in the filter.
I turned it off immediately. I knew I wasn't allowed to pull him out (didn't want to hurt him), but he had trouble coming out by himself. Eventually we made it, but one eye seems to be hurt plus he has a big wound on his back (scales are missing).
I cleaned up his tank immediately and stuck a piece of sponge in the opening of his filter, so he won't get sucked in again.
He won't eat, don't even know if he is able to eat.
I'm very afraid to lose him and don't want him to die.
Should I go to a vet? (I'm sorry, I really don't know very much about fish! Our pet store assistants here don't know very much unfortunately, so I really don't know who to ask for help.)
How can I help him?
Thank you in advance!!!!!
