This discussion has come up before but I have attempted to wage war on these bumps that grow on some neon tetras lips. I’ve tried clean, daily water changes with salt, Erythromycin, and herbal bacterial meds. I’ve read Spectogram is the best for it so going with that next if no one has a better suggestion. Pic below. Anyone had experience with this? It really appears to be viral and only affecting the neons. Tank is a 20G long heated to 76F. 0 0,5 as of last night. PH always stable at 7.6. Haven’t tested KH/GH In a while but always steady in range. I can test this afternoon if need to.
