Grey Smooth Hound Shark

Grey Smooth Hound Sharks originate in temperate waters of the eastern Pacific, primarily from California down to Mexico. While they are active fish that swim most of the time, they tend to stay near structures and the ocean floor in order to avoid larger more aggressive shark species. Grey Smooth Hound Sharks have sharp teeth and are true sharks, they are not harmful to humans and are highly unlikely to bite a human unless provoked. This species is considered suitable for expert marine aquarium hobbyists with very large aquariums due to their relatively small size (3 to 4 feet) and active but slower swimming style.

Grey Smooth Hound Shark

In the home aquarium environment, Grey Smooth Hound Sharks should be provided an aquarium that can comfortably support their adult size of approximately 4 feet for female specimens and 3.5 feet for male specimens. They should be provided an aquarium that is at a minimum 4 times the length of the shark, twice the width of the shark and twice the height of the shark, thus this would mean an aquarium similar to 16 feet x 8 feet x 3 feet in size. Young Grey Smooth Hounds can live in aquariums as small as 450 to 500 gallons in size, but will need to be moved to a larger aquarium or pond within 1 to 2 years time. On average the Grey Smooth Hound Shark is born at around 9 to 12 inches, will grow 6 to 8 inches per year until reaching its adult size in 2 to 3 years and will live an average life span of 6 years for males and up to 9 years for females.

Like other shark species, the Grey Smooth Hound Shark should have a smooth sandy substrate, plenty of open swimming room with some rock or coral structures and a secure top to the aquarium to prevent the shark from jumping out. They have a thick muscular body for a shark their size and will put a significant load on both the mechanical and biological filtration. Therefore, filters for shark aquariums should be able to process large volumes of water and be able to efficiently remove large volumes of fish waste from the aquarium. It is recommended that a shark aquarium have a very large protein skimmer, significant biological filtration and regular water changes in order to maintain high quality water within the aquarium.
