10 gallon tank
when I bought home the neon tetra I notice one them didn’t have a bottom jaw, he died shortly after, then noticed 2 other tetra also had it and they died, out of 9 neon 4 died. They are in a tank with 2 glo tetras. I started Maracyn treatment and didn’t treat ich until after the 1 course, but noticed they now have fin rot. Finished 2nd course of maracyn not much change. Not sure what else to do.
This is my hospital tank not sure if I should sterilize the tank or what other steps I should take. I tried the soak method for 4 days. First photo is the no bottom jaw pic, last photo is most recent.
