is there anyway to tell physically? like do male have a duller center of the body and female stay brighter fully through? i have noticed this in alot of pairs i have been seeing so i was wondering about that. also, if there was a female in spawn mode and you put in a random large male would that male go into spawning mode? i had a pair that was about to spawn again and my male died. the female is still ready to spawn and i got another adult discus that i think is a male. would they have a chance at spawning or would it be a long process. would the male start the prespawn tube dropping due to the females prespawn state?
