Saltwater fish are some of the most beautiful fish in the aquarium hobby. Full of bright color and personality, these fish are also some of the hardest fish to care for in a fish tank. Many saltwater fish are harvested straight from the sea. Others are tank-bred and live in captivity their entire lives. There are even extremely small fish taken from their schools and tank-raised. These fish allow people in the saltwater aquarist hobby to enjoy these fish while maintaining balance in the natural ocean habitat. If you own a saltwater tank, revel in the beauty of these amazing fish.
