A group of polliwogs, which are the larval stage of frogs or toads, is commonly referred to as a "school." These young amphibians are often found in ponds or marshes, where they swim together in large numbers during their developmental stage.
When the sperm and egg of two animals meet, they create a zygote. It is then called an embryo during the early stages of development and later called a foetus.

Some people call tadpoles "polliwogs". I believe it is a British term.
They eat anything from algae to dead polliwogs. You can put in things like algae tablets but that is pretty much optional. To recap you really don't need to put anything in it until they are frogs. Hoped this helped!
