Gah.. I was afraid of that.
I really really want a female!
I've got two options - go back and check the remaining siblings of this brood for a female next weekend, or wait until these guys are fully grown and get an adult female from another source.
I'd like to house all three of them together in a 30 gallon, but not if it's risky for them. I could start another 20 gallon for a lone female, but I would really like to try to keep the Emps to one tank.
Any thoughts on the best course of action?
