well i got them to lay eggs but they never hatched, i seen my gulpers mate lately but they havent laid any eggs, im thinking they prolly breed once a year? ill keep u guys up to date if they do lay eggs again, i messed up the first time because i took out the male after the female laid her eggs because i thought he would eat them all. btw i think they need drift wood to lay eggs on, they laid eggs all over my drift wood.
