Woven from seaweed, scultped from sand and carefully blown into bubbles, fish nesting and parental care is breathtaking in its diversity, and offers a glimpse inside the minds of our little finned friends. 

On today's show, Tessa Campisi speaks to Professor Bob Wong of the school of Biological Sciences at Monash University about the breathtaking nest building behaviours of fish.
