The Caterpillar children helped with the regular clean of their fish tank. The children helped to scoop the fish named Tom from his tank using a net and placed him into a bowl of water. The ornaments and stones were removed from the tank and thoroughly cleaned. The water was removed from the tank and the children helped to give the tank a good scrub. Once the tank was gleaming again, it was refilled with fresh water, the stones and ornaments replaced and then Tom the fish was put back into the tank using the net. The fish was then fed with his food.
