How long you keep this french ? Is it a new member ?
Does your french still eating and healthy ?
My french also have this problem after I bought it 1 week, but not that serious like yours.
I just changed water more frequently and she is getting well now after 1 month.
Where is your french come from ? Brazil or USA ? I heard someone said it is not easy to keep a french com from Brazil, USA french is easiler to keep. Any expert in here can tell me is it correct ?
