Character and suggestions regarding care

This fish is peaceful, however it should not be kept with very small species.

Longhorn Cowfish can grow up to 45 cm what is approximately 17 inches. So 1 specimen requires at least 5400cm² of water surface which is approximately 837 square inch. It is recommended to raise this species in fish tanks that are large. (e) Medium aquariums have at least 113 Litres (30 US Gallons). Large aquariums have at least 265 Litres (70 US Gallons). Very large aquariums have at least 700 Litres (185 US Gallons).

It is difficult to keep the Longhorn Cowfish. (e) The specific gravity (SG) should be between 1,020 and 1,025, the temperature between 23°C (73.4°F) and 26°C (78.8°F). The recommended pH level is between 8.0 and 8.3 since marine fish are used to these levels in general.

This fish might be dangerous for all fish in the tank. If it is stressed, it may release a toxic substance, which can kill other fish and creatures in the tank if you do not change the water quickly.

L. Cornuta should be not kept with aggressive and quick swimming fish or other Cowfish.

Longhorn Cowfish is an omnivore and it can be fed worms, clams, tunicates, various mussels, snails, shrimp and algae. It will accept these food in live or frozen form.
