My male gold severums are currently locking lips. The two just started locking lips and are practicly magnetic because when I seperated them with my net they went right back to fighting. The aggressor, whom I call Red (because of his blood red eyes), is definatly getting his anal fin handed to him by Jimmy (he just looks like a Jimmy to me). I just changed water and I was wondering if that may have triggered it and the two are housed with a female in a 75 gallon. Should I return one of the sevs?
