If I were to buy two young cresties and was unsure of their sex, but when they got older, one was a male and one a female, will I have to separate them? I'm not planning to have crestie eggs! :wink: Also, if I were to house the young ones in a sterilite bin, would it get too humid in there? What would be good dimensions for the tank to keep 2 young cresties? Thanks!
