Started my first communal today. A dozen Neoholothele incei (not from the sac I just hatched). Within minutes they were eating together after being unpacked - was so neat seeing them piled on top of the same prey item.
There are a dozen in this container and although I provided many hiding places and premade burrows, I came home to find the majority of them all clustered together. I look forward to providing updates on this little group - fingers crossed it is a success.
