I am doing a science fair project and I wanted to test the effect of different fertilizers on the respiration and behavior of the fish. I want to use pennsylvania native fish for my project and have at most a 55 gallon tank. I would only need to test one species. All I'm looking for is a small fish that is able to be bought somewhere for a reasonable price. Thank you for all of your help!
Pennsylvania wildlife fish?
