Today I noticed one of my fish sucked up against the filter intake and appears to have lost its tail. Yesterday it was not like this... I have removed the fish and put it in its own hospital tank for now (for the past 30 min now). I just want to make sure Im not putting it through pointless pain and me wasting time trying to save it if its obviously not possible. It is a glofish danio. And yes, until tomorrow morning the hospital tank is a 5 gallon bucket with an air stone running. Its all I have for time being.
