Fortunately my Conjag with columnaris recovered and is doing great. Unfortunately my Wolf Fish died during the night. I didn't realized that it was so contagious, i have another tank full of Conjag fry, but i don't share any equipment with them. But will make sure to really disinfect my hands if I am going to be working on both. I am assuming I should continue the amoxicillin treatment as well as the Pimafix as a precautionary measure. Because from what I understood, even if the remaining fish are not showing symptoms, that does not mean that the infection is not there. Am I doing a lot of damage to my ben. bacteria with the amoxicillin?
