Couldn’t find any of the above mentioned myracin2, kanaplex , etc. in PetSmart or Petco
I did find erythromycin which showed both symptoms on the box. (I have kanaplex showing up on Thursday). Plan is moving him to a different tank and dosing erythromycin. Water will be part DT water and part freshly made. Question is will an air pump and stone work or do I need to use a sponge filter? If it’s the sponge filter do I toss the sponge when done or just clean it? Heater and temp monitor. @vetteguy53081 , @Jay Hemdal
One issue with erythromycin is that it is most effective against gram positive bacteria, and most fish pathogens are gram negative. It can also harm your beneficial bacteria. Can you use some filter media from your main tank to help offset that?
