Remove remaining scraps from the tank three hours after feeding to avoid fouling of the tank. Algae can be removed from the sides of the tank with a paper towel or scrubber. Be sure not to use any detergents or cleaners in or around the tank. Also, do not use the scrubber for any other purpose. The tank should then be set up elsewhere for the summer so that the aquarium may once again be used the following school year.
Restrictions prohibit the release of the organisms back into the environment.
For another activity to do with the aquarium, see the following enrichment activity.
