will convicts foster other convict pairs fry? i always seem to have a mass spawn (4-5 pairs) in my tank after a water change. all the fry hatch within hours of eachother could i place all of the fry with the best set of parents in a fry tank? will the parents know that most of the fry are not thiers...i have mixed pairs some black x pink, black x black, marble x black,.....etc....
