I was lucky enough to get a hold of 5 of these wonderful little shellies and I put them in a 40 long along with 6 Utinta Cyps (2 male 4 female). Every now and again I will see a few little babies and then within a day or two they are gone!! I'm wondering if its more likely the other shellies or the Cyps that are eating them. And what is my best options to try and get some of these little guys to survive. Also, are the darker ones the males and lighter ones the females?
