It started as a couple on a single rock and next thing you know bam, the tank was full of them. I don't have a tds meter to take a reading, will look into buying one soon. I myself never poped any inside the tank, but they pop when thay get big and they do get big. The crabs don't pop or eat any of the big ones, it seams they just like the ones starting out. Would it be a good idea to get another half dozen crabs to bost my total count to 12.
