Ok so my step dad bought some feeder minnows that are being kept in my 30gallon tank, and now they are developing some illness their back half is turning white and discoloring and their tail fins are shreding to the point there is nothing left and are having trouble swimming, this has already killed 2 minnows and another 3 are infected. What should I do, What is it, how do I treat it and after the minnows are gone do I need to scrub it down before I can put more fish in it?
Heres a crummy cellphone pic of it if needed I can try and get a better pic with my sisters camera.
