most of the fish in my tank have all come from the pet shop in question and ive always been happy with them. However i called in yesterday to see if there was anything new and was kinda worried about the amount of sick fish in the tanks. I think its TB they had (bent spines). There would have been between 6-8 fish in total all in different tanks and it isnt a big shop. Should i stop buying from here or could it just be bad luck, any comments appreciated
