The Best Non Aggressive Saltwater Fish

A saltwater aquarium can be an interesting focal point for your home. The sound of the water and sight of fish can have a calming effect on pet owners. Owning fish is also an excellent way to teach children the responsibilities of caring for a pet before allowing them to progress to larger animals. When choosing the type of fish for your aquarium, aggression levels are important factors because aggressive fish will kill non-aggressive fish.

  1. Auriga Butterfly Fish

    • The Auriga Butterfly fish, commonly called the Threadfin Butterfly fish, is a popular saltwater aquarium fish. It exhibits splendid colors that vary depending on the region of origin. Many fish contain a false eye on the dorsal fin to confuse predators, but those from the Red Sea don't always have this spot. The Threadfin is a shy fish that won't bother other non-aggressive fish in your aquarium. They require several hiding places, which can be made from real rock or aquarium decorations. These fish live primarily on plankton and flake food, but benefit from the introduction of a vegetable food source and vitamins.

    Firefish

    • Firefish are also known as Firefish Goby, Fire Goby or Fire Dartfish. The Firefish is a popular saltwater aquarium fish because of its brilliant color and body shape. Their heads are yellow with a small amount of purple on top. The top half of the body is white and the bottom half varies in color from pink to orange-red. Firefish are well known for having vivid personalities and displaying non-aggressive behavior. They are very timid fish that require several hiding places when they feel threatened. Firefish may display aggression toward others of its species, but mated pairs can live together. Firefish mainly eat algae and zooplankton, but also enjoy small crustaceans, brine fish and mysis shrimp.

    Bicolor Blenny

    • Bicolor blennies are small, bottom-dwelling fish that only grow to about 4 inches in length. It gets its name because the front of its body is a blue or brown color and the back half is yellow or orange. They commonly feed on marine algae and are excellent for keeping aquariums clean. Blennies are generally a very peaceful saltwater fish, but they can become territorial if forced to live in a small aquarium with other bottom-dwelling fish. You should also avoid placing them in an aquarium with aggressive fish and provide them with several hiding places along the bottom of the tank. A male and female pair can live peacefully together, but spawning in captivity is very rare.
