Would it be possible to keep an M. Barbarus colony on an island to prevent escaping?
I'm considering a 80x40x40cm terrarium with a canal/moat around it of 5cm wide and 5cm deep. With a small current provided by a pump.
This should (if they cant swim) keep them on their island. There would be a floater getting acros every now and then and some would drown.
Has anyone tried this before? Does it work?
