Some corals, such as sun corals (Tubastrea sp.), need occasional spot feeding in order to thrive long term in an aquarium. They don’t rely on photosynthesis as much as some of the other species available to the aquarium trade, and must make up for this by consuming large food items. Unfortunately, any feeding activities aimed at the corals also draw the attention of hungry fish, which will steal food well before the coral has a chance to eat it. To protect the feeding process, hobbyists can put a piece of tupperware (with multiple small holes cut into it) over the coral and inject food onto the coral. The tupperware will keep the fish from stealing the food and can be removed once the coral is done eating.
