Swordtail with bad mouth

[Arch]

Hi folks - i have a swordtail who just give birth last night so i put her back into the original tank this morning. Now i notice her mouth has like bits of skin hanging off it and some of the other fish are chasing her. She ate ok when i fed them however she is staying up round the top of the tank at the filter box and this is normally a bad sign. Any ideas?

Take her out asap. Just had the exact same thing happen to my oscar (except he came back from the hospitol.) Take it out and keep it seperated. She probably just got into a huge fight. My oscar and My jack dempsey went at it while I was at work. Tore a tiny piece of blindy's lip up so he had to go back into the hospitol (he hates it soo much!!) Also tore a little bit of his mouth out. Probably just being territorial your other fish were. This happened Thursday I think and here 5 days later he is mostly healed and ready to go into another tank until I move his first one. Gonna have to completely change the decor around so that nobody has any territories. U too I think.
