I have a female dwarf gourami and another gourami, male i think (he is red and blue and has darker stripes) the male keeps "sucking" at the female gourami. Its worrying me as i dont want to find one of them floating on the top when i wake up tomorrow. He does it all over her body and keeps chasing after her so she does it back! Anyone tell me what they're up to?
thanks.
thanks.
