Please explain better, i dont quiet understand?
First of all DO NOT treat them with any medicine! this i have found is normal behavour in males, not nessecarily females, without evedince of sickness, such as physical appearance or swimming difficultys, you shoudl not treat with any kind of medication, Find out the problem then treat the fish. Personaly i dont know how somone can diagnose an illness as ich, when it has been described as a behavioural feature not one of sickness, sugestion at most if really worried, do a water change and add a bit of tonic salt. as always with livebearers, if they contract ich then you should treat with salt not other medications, salt is more natural and they live in a highish silinity quite nicley. All my livebearer tanks are "salted" so to speak.
