Well she is pretty small as are the others in the tank so they are all young. 0 ammonia, 0 nitrite, and <20 nitrate. It is hard to tell if she is thin because she is so young, a little over 1/2 inch. She is a little pale I can say, but she is about as pale as the other Rams with the exception of the dominant male, who is usually brightly colored. She is not swimming irregularly or flicking against anything. The only thing that really seems wrong with her is her blood red gill area. It looks like the color comes from underneath her gill cover so I am pretty sure i just got a sick fish. There were only 3 Rams left when I got her, one has torn fins but her and the other I picked up looked OK. I may just take her back and get some other fish instead. Unless anyone thinks that it is possible for her to recover from this?
