Hi everyone, I got a betta fish last Christmas and has been fine ever since with no problems at all. But just around half an hour ago I went to pour it into a separate cup to stay in whilst I changed its water, but it missed the cup and fell in the sink and then the cup fell on it. I wasn't to worried until I placed it back in its tank when it just floated to the bottom and layed their but still breathing. I then realized when I carried it back into my room it moved a bit but only one of its fins (the ones next to its gills) was moving. So I'm just wondering whether to just leave it and hope it recovers or do something. Any help would be very appreciated :-(
