So I've had this pair of E. johnii since they were 6 month old babies. Was told originally that they were male/female unrelated pair. For some reason I never really got around to probing them. On a whim decided to do it today... no idea really why. Discovered I am now the proud owner of two happy healthy unrelated MALES. ARGH! Funny thing is I'd been toying with selling the pair for about 6 months... I guess it was answered for me.
