I understand this is saltwater forum but with all the knowledge here I feel someone can help. I have a freshwater arrowhead puffer who is not eating and seems unbalanced laying on the bottom. Hes usually very reactive when offered food but in the past week hes only eaten one bite i had to shove in his mouth and after spitting out several times he finally swallowed a small piece. Ive done several water changes and have added salt since. so testing the water after didnt tell me much.
