Hey guys, Something is wrong with one of the female guppy that I have. First I thought it's stressed out, it gets beaten up by an endler female. She swimmed for hours in the flow produces by the filter. After 2 days I've noticed a white stuff on her mouth and head, I decided to put her in a fish maternity and see if she will do better but the white stuff spread on her body also, can you please help me identify the problem and what treatment should I use. The parameters are in check nothing out of the ordinary, temprature between 23-24degrees Celsius ( 73-74 Fahrenheit). The other fish are ok. here is a video: http://cl.ly/422g3r2b1e0d Thank you!
