I noticed tesselate darters have an amazing ability to match the substrate turning from pale and speckled in sand to reddish brown and pale over mud.
How do they know how to match the environment they are in? Know is in quotes as I know it is not actual knowledge driving it.
What do they hide from? Is it just a generally useful defense or is it to counter one specific predator who targets them?

Hiding from anything that might eat you is a useful trait. I can imagine any number of animals would consider a Darter a tasty snack, other fish, birds, coons... I assume this trait has been selected for.
