Hi everyone - my father has gone away on holiday and left his betta fish in the care of a family friend. I visited a week ago and he (Bob the betta) wasn't looking so good, upon coming back now he looks awful. I can't really answer the below questions very well as I don't know anything about fish, have read up on symptoms and not sure what he has but not feeling hopeful. Is there anything I can do to save him?
