Are you asking if you can stick your finger in it's tank without being bitten? Yes. Yes you can. Betas are only really violent to other Bettas or fish with similar colouring so unless your finger looks remarkably like a beautiful three inch long fish with flowing fins, you should be just fine :)
If the Beta Fish doesn't eat then it means that the Beta Fish is sick. I know this answer because I had a Beta Fish in my class in grade 4.
a gold fish or a beta fish
a beta fish is one.

First thing would be removing the fish that is attacking the Beta's fins. If it is not a fish, the Beta may have a disease such as tail rot-in which case you need to isolate the fish and treat it. But there are supplements that can help with the health of the fish.
The vagina is said to smell slightly like fish, so someone with a "fish finger" would be someone who had stuck that finger into a vagina.
I suppose it is possible. Beta are very territorial fish.
ARMAGEDDON!
A fish bowl is not a solution its what you keep your goldfish/ beta fish in :P

Beta fish don't get along with other fishes, they will attack any fish that they see as a threat. If you buy a female and a male beta DO NOT put them together.
