I was just thinking - a good fish for such a study would be the Sculpins (family
Cottidae). There are lots of them around here in various habitats and they are 
fun and
easy to keep in the aquarium. They show a lot of special adaptation. 

Check this site:
http://artedi.fish.washington.edu/FishKey/cott.html

  "This is a very large family with about 300 species. Most species are found 
in Arctic
or temperate waters and are bottom dwellers. They typically occur in shallow or
intertidal zones, though some   species occur in deep ocean and others in fresh 
water.
All species are oviparous; some have internal fertilization. Eggs are usually 
deposited
among rocks and are guarded by the male while they develop.
 Most species have cryptic coloration (brown or green to blend in with silt and 
algae).
Sculpins are generally small fishes of less than 30 cm. Our largest species is 
the
Cabezon, which grows to a maximum of about 1 meter. The Cabezon may eat fishes, 
but
smaller sculpins feed mainly on small invertebrates. All sculpins are important 
food
sources for other fishes, though most cottids are too small to be palatable to 
humans.
This is a common family in Puget Sound, with 35 species recorded here."
