Frustrating little buggars aren't they. Maybe we should just use them as
anchovy substitutes on pizzas ;-)

I wonder if the eggs (or adults) need exposure to sunlight. Maybe for

aspects. Anybody have any ideas.

I suppose we persist with our breeding populations (until we eventually
develop a strain suitable for captivity) :-(
