So I just brought my EBJD home from my lfs about a week ago. On the first day he/she seemed to fit in quite normal. The following day and ever since he/she has been swimming up and down and left to right on the back side of the tank. Pretty much non stop. He/she stops for a short time when my GT gets close but then when gt goes about his business my jd starts it back up again. There is no visible signs of diseases or infection. Although I have seen him/her itch on decor in the tank a couple times. My GT has also done this itching a couple times since the new fish has arrived. May this all be normal fish business or could it be a sign of an internal parasite?
