Hi.My name is Flavia.9 months ago i bought a female beta fish.She was doing fine.Eating well, happy etc...One week ago i noticed she had a bump on the beggining of her tail.I thought she was gravid.Then she started to weird swim.She swims on her sides or upside down.But she is still eating well but the bump is still there too.Whats going on?
Thanks for any advice.
Flavia
