River Model

The river model has 4 different tubs with different "environments" and four pipeways between each one. We want to observe the patterns of which tubs the fish reside in. On Sept. 5 we had 23 of the 26 fish left due to pump death. In pool 3 there were 20 ghost shrimp and no minows, 2 brown minows in pool 2, and and orange & brown minow in pool 4.
