Having Your Longhorn Cowfish

Longhorn Cowfish Care
As the longhorn cowfish in captivity live less than that in the wild, caring becomes tedious. They feed on fleshy marine algae and require a tank that can hold 100 gallons of water.
The water must be cleaned regularly as they tend to secrete poison and poison-like substances. They must also have a strict diet as aggressive feeding can lead to complex problems with the longhorn cowfish and other fish in the aquarium.
