Have you ever had a fish tank in your classroom?
Caring for fish can be a terrific class project. In our classroom, our teacher, Constance Krauss, and two high school teachers, Brad Sajeski and Thomas McCarthy, set up a 25-gallon saltwater fish tank. Our tank was donated by Sanseviro Insurance Agency of Sayville.
We added saltwater and sand from Great South Bay. Mr. Sajeski and Mr. McCarthy caught several kinds of fish for the tank using a net. They videotaped their trip to share with the class. Mr. Sajeski is a high school science teacher, so he knows a lot about marine life.
Seashells were collected along the shore of Fire Island. Students have been observing the different species and how they interact. We have hermit crabs, a whelk (sea snail), killifish and baby shrimp. We really like the way the tank is set up.
We have make sure the tank is always clean, the fish are fed, and the filter is running. And we check the water and salt levels.
We never realized all the work that goes into keeping a saltwater tank clean and
running. It is both exciting and interesting to watch.
Sometimes, if we are having a bad day, it's nice to just walk over to the tank and watch the fish swim. We also like the way the sunlight shimmers through the grasses and listening to the filter's hum. It relaxes us.
