i went to a pet store at the mall and they had a new shipment of black convicts... so after careful observation i picked out the two that seemed to have paired off. after getting them home and into the tank after letting them sit, they have eaten already, but i am wondering how long would it take for the pair to pair back up? i mean they had eggs laid in the tank at the store. but now they seem to show a little more aggression towards each other. is this normal and would they eventually pair off?
