Longhorn cowfish - A Poisonous Pet

Longhorn cowfishThe Longhorn cowfish is one of the strangest-looking fish ever to swim in an aquarium. It's actually not well-suited to life in captivity, thanks to its ability to release ostracitoxin when stressed. This can have bad effects on a tank's other inhabitants. However, the Longhorn cowfish's odd appearance has made it quite popular with saltwater fish keepers. It is a type of boxfish, a group of fish that is related to the more widely recognized Pufferfish family. Most fish stick to the standard, streamlined shape, but all cowfish have a blocky, boxy shape that makes this group unique and easily recognized. The Longhorn cowfish's standard color is yellow ranging to olive with white or blue-white spots, but other morphs exist with orange or green coloration. The fish's defining feature is the set of horns that protrude from the head; they're much longer than the horns of any other cowfish.


Maximum adult size - about 50 cm, or 20 inches.

Weight - Most captive specimens are young and don't weigh more than a few ounces. A large one might weigh in at a pound or two, or .5 to 1 kilogram.


Obviously, longhorn cowfish are not particularly large fish. A 6 inch fish would be considered large at a pet shop. In the wild, the longhorn cowfish is most often found on and near reefs of the Indo-Pacific region, but it also lives in still bays, harbors and estuaries with sand or mud bottoms. Young fish are often associated with Acropora corals.


The longhorn cowfish generally sticks to shallow water from 1 to 50 meters. They may be found in water up to 100 meters deep, but this is not common. Longhorn cowfish range from the Red Sea all the way to Australia and southern Japan, and they also live along Africa's southern Atlantic coast. They are not endangered, and they're common enough to be found in pet stores. Like many popular aquarium fish, longhorn cowfish are not found in the Americas.


Most boxfish are slow swimmers; they can actually be caught by hand. The longhorn cowfish is certainly not an agile hunter, so its diet consists mainly of invertebrates and benthic algae. They have even been observed blowing jets of water into the sand to uncover delectable worms. Larger fish also eat other fish when they can. Between their poisonous flesh and their scaly armor, cowfish are unattractive to many predators. The horns on the head and under the tail are thought to make the fish hard to swallow. Even so, longhorn cowfish are sometimes eaten by larger predators like albacore and bigeye tuna.
