This platy was in a tank that had a nitrite spike. I was uneducated at the time about cycling but I have done lots of research and I am trying to do better now. So I have a couple of problems, first of all I don't know if the way her fins look could have been caused by being in the tank with high ammonia and nitrites or if it is something else. My second problem is she is currently having fry and I don't know whether to move her out of the tank when she is finished or if I should move them (I know it is risky to move fry) because whatever this is could have contaminated the tank they are in. I have a 55g I can move them to in a separate breeder box ( I have my other fry in there already), or I can put mom in a quarantine tank and leave fry where they are.
