Hurt Female?

Ok so my female, Cleopatra, looks like her tail has been bitten and has now lost all its color and most of its volume. She is having a hard time swimming and is being pestered by the males so I put her in the breeder box alone to heal. I hope she will recover. I don't know if their tails can grow back. I will have to do some research to find out. She seems to be hanging on for the time being though. I'll see if she makes it through the night.
