The biggest male is in a 75, the smaller male is in a 40 breeder, 2 females are in another 75, and the smallest female is in a 40 breeder. I'm supposed to be picking up a third 75 tomorrow hopefully. I take turns giving conjugal visits in the 75's. Hopefully I'll get lucky with some eggs. I've never tried breeding them before but I read a ton about it and have two laying boxes ready so I'll keep my fingers crossed and wait and see.
