If hes in a seperate tank u can add a little bit of kosher salt might help but only use half dose of meds tetras are very sensitive to this type of stuff regular doses can kill tetras
Yes just different names it looks like salt Drizzled on him when i put my first post on here my fish had ich to but i raised temp and medicated and it went away
If he has ich u need to medicate right away and raise ur temp to 82 f and leave it ther for atleast 14 days but in 3 days the spots will be gone ... use half dosage for tetras... I used nox ich and it worked good luck man
