red tubeworm - Serpula vermicularis
Photo showing three brightly coloured Malawi cichlids in a large landscaped fish tank.  The aquarium has fine coral sand on the base and lots of rocks, to provide hiding and sleeping spaces for the fish.  Malawis are known for being 'messy' fish and require a particularly good filtration system.  As they are such stunning colours, many people mistake them for saltwater marine fish, although they actually live in tropical freshwater.
