Recently I had a fish with parasites, I treated him but he remained in the hospital tank. Now i had a new problem with a fish swimming straight up and down. So I moved him to the hospital tank as well. Now I see a curve in his spine and he does not move his back fin very much if at all. After treating him in that tank his behavior is better but he still has the curve. Now I went and looked online and it says it could be fish TB I put my hands in that tank like 6 times now before i heard it can be transferred to humans (crap I hope i will be okay). Now the silver fish is fine but I am afraid to put him back incase the platty gave him TB as well. Is there any other disease that can give him a curved spine? That is the ONLY symptom he has of it.
