What fish you get depends on what you want. You could get a lot of small fish or just 2-3 bigger fish.
In some filter setups there are 3 filter medias inside them. Mine has a spnoge filter, with ceramic tubes and carbon bags. THe sponge catches the large debris the carbon clean the tank out and the ceramic disks are for forming bacterial colonies for creating a good chemical balance onside the tank
