Sick bichir - awkward floating

how long did you treat last time with antibiotics?

I would agree that it seems more a bacterial thing than not. if you started treating with an antibiotic and then after a day or two you stopped the infection can easily return and may become resistant to the antibiotic. Like with people when treating with an antibiotic, it's best to treat for a week at a time and go from there...
 
He is still floating awkward... And yes the last time I treated with antibiotics it was for about 6days. 1 day past the reccomended dosage on the box, but since it was for fin rot once his fins started to grow back I stopped treatment thinking the infection was gone.

Should I try tetracycline again? Or should I wait a little bit longer. His back end is floating now, but like I said sometimes I see him sitting normally on the bottom, and there are no red streaks of any kind.... I don't know what to do.
