Ok, so a few weeks ago my green terror slowly lost his appetite and had white stringy poop. The most common thing i came across when researching this was internal parasites.. Since then I have treated with paraguard and seachem metronidazole. (seperate times) I also added epson salt because I read this might help. Diet isnt the cause for this because he hasnt eaten in a couple weeks and is starting to get thin. I have also treated with melafix. Tonight I noticed he was acting even stranger by shaking his head.. I really don't know what else I can do. Any suggestions?
