Accidental X breeding I have two female Convicts (Amatitlania nigrofasciata) and one Male earth eater (Geophagus steindachneri) in a 40 Gal. I have done well even with the mild tempered earth eater with my aggressive convicts. Recently the eartheater has started shimmering or convulsing, and none of my fish would eat this morning. What could this be besides breeding behavior? is there a way i can deter them from mating? i have no desire for a cross breed.
