Is my male molly trying to get it on with the female? Hes really harrassing her, and sticking his top fin up in the air all the time like this!

He will pay close attention to a female and display his huge sail fin when he is interested in mating. If you only have a single female, the constant attention can become too much. That is why we recommend at least 2 or 3 females to each male when livebearers are kept in small numbers.
