Setting up a fish tank provides great enrichment in a classroom. Although I attempt to make the students responsible for feeding the fish, I find they can often be heavy handed in giving the pets just a pinch. My solution was to purchase a pill reminder box that has separate lidded compartments labeled for each day of the week. I fill each day with the exact amount necessary and place it next to the tank. A student helper opens that day’s compartment and feeds the fish. I can easily check to see if they’ve been fed, I’m certain of the amount and every student gets a turn at feeding.
