haha.....my fantail swims upside down for a good min or so at least once or twice everyday...the amonia ph and nitrates and nitrites are all normal...he swims the right way most of the day then all of a sudden he gets goofy on me and starts swimming upside down...i dont think this is normal...do i just have a special fish on my hands or is somthing wrong with him...he looks perfectly fine when hes upside down...i just dont know why hes doing it...it just started this week too
