Alright heres the deal I got three females for a five gallon tank. When I brought them home I realized one wasn't doing to well so I put her in empty one gallon using water from my 37 gallon she was breathing rapidly and not being very active and had black eyes, she is also pretty big and I think shes just getting old. After alcumating the other two I put them into my cycled five gallon. Then I went to go eat then I came back and they had there jaws locked and fighting they both had torn fins and one had wounds on one side and there fins were some what clamped and they both had velvet I put the wounded one into a breeding box. Now what do I do? I dont want to buy any medication because I dont have a LFS I only have petco and petsmart
