How do female sticklebacks decide which basket to put all their eggs into? How did they convince the guys to do all the housework, tend the babies, look after the bigger kids and build the house as well, all while they pursue their dreams? What does a luxury stickleback pad look like anyhow? And what are just bare necessities of stickleback life?

Why, given the pollution in their silted up home, are they still there? They could have moved up stream? Does that mean that they’ve learned to cope with not being able to really see each other, large amounts of lead and the absence of aquatic plants? how did they do that?

If sticklebacks eat crustaceans, and the crustaceans eat the algae, could we clear the water by removing the sticklebacks (temporarily) and increasing the crustacean population so they eat more algae?
