The Porcupine Puffer Fish (Diodon holocanthus)

Porcupine Puffer Fish

The Porcupine Puffer Fish (Diodon holocanthus), also commonly called blowfish, balloonfish, spiny puffer and globefish are fish belonging to the family Diodontidae (order Tetraodontiformes). They are collectively called pufferfish, not to be confused with the morphologically similar and closely related Tetraodontidae, which are more commonly given this name.

The Porcupine Puffer Fish are medium- to large-sized fish, are widespread and can be discovered in the Atlantic Ocean, in the Pacific Ocean, and in the Indian Ocean. This fish is an egg-laying species and breed in pelagic waters. They do not guard their offspring.

A few species are discovered much further out from shore, in which large schools of thousands of individuals could occur. They are typically slow and young Porcupine Puffer Fish are pelagic while adult specimens prefer to stay inshore.

The Porcupine Puffer Fish is an odd looking fish that has the obvious ability to inflate their bodies to twice its original size by swallowing water or air, thereby becoming rounder. This increase in size reduces the range of potential predators to those with much larger mouths. Additionally, their inflated bodies are covered in short sharp spines making it very tough for a predator to take a bite.

Some species are poisonous, having a tetrodotoxin in their internal organs, such as the ovaries as well as liver. This neurotoxin is at least 1200 times much more powerful compared to cyanide. The poison is produced by several types of bacteria obtained from the fish’s diet.

As a result of these 3 defenses, Porcupine Puffer Fish have few predators, although adults are occasionally preyed upon by killer whales and shark. Juveniles are also preyed on by Lysiosquillina maculata, tuna, and also dolphins. To prevent from this happening try to scoop or direct them into a bag when moving them. However, do not use a net to move them.

In the ocean Porcupine Puffer Fish could frequently be discovered in small groups, however, replicating this in the home fish tank can be foolish because of their potential adult size and because they can be one of the dirtier fishes to keep. Although the Porcupine Puffer Fish is easy to feed and generally hardy, they require special care and a special diet to stay healthy.

The Porcupine Puffer Fish will typically reach about 12 inches (30 cm) or more so you’ll need to have a larger tank, preferably 90 gallons (340 liters) or larger. For most hobbyists, keeping multiple Porcupine Puffers would not be a good idea. Naturally, this puffers inhabitant requires salt water within 25°C-28°C. The Porcupine Puffer Fish can be fairly long lived in the fish tank, many living for 5 or more years.

However, it is essential to be aware of them if you’re considering this breed. The Porcupine Puffer Fish diseases are mainly the same as those that afflict other saltwater fish, and also the symptoms, as well as treatment of saltwater fish, are also similar.

Marine ich is a condition that affects saltwater fish. Although there are some infections that have similar symptoms, ich is a distinct illness caused by a parasitic infection. The Porcupine Puffer Fish are especially prone to developing this illness, and also treatment can be difficult. Ich has a number of distinct symptoms.

 

Diet Of The Porcupine Puffer Fish

Diet Of The Porcupine Puffer Fish

The Porcupine Puffer Fish are primarily carnivorous, which means that they feed just on meat. They eat crustaceans in the wild and will accept most types of marine fish food consisting of frozen, freeze dried, and also live food.

The Porcupine Puffer Fish requires a varied diet of meaty foods consisting of krill, squid, clam, and also hard shelled shrimp. Small pieces of fresh shrimp and also clam can be chopped up and given. Provide a variety of foods, however, mostly meaty items for optimal health.

Additionally, the Porcupine Puffer Fish have strong teeth that grow throughout their lives. The hard-shelled shrimp is essential, as they need to be provided hard shelled live food frequently to keep their teeth worn down. And provide some of the herbivore frozen foods a couple of times per week and also try to get them to eat vitamin enriched flake foods too.

The Porcupine Puffer Fish require a large fish tank, preferably 90 gallons (340 liters) or larger. Since they could grow up to 12 inches (30 cm) or more. They should be kept in salt water at a temperature between 75°F (25°C) and 82°F (28°C). The pH level should be between 8.1 and 8.4, are recommended. Not suitable for a reef tank setup.

The Porcupine Puffer Fish is not a picky eater and will quickly become adjusted to a variety of prepared aquarium foods as well as an occasional algae wafer. Require a strong canister filter or protein skimmer will considerably cut down on the need for water changes. Additionally, puffers eat a meaty diet and are typically messy eaters, they will produce a large bio load on the biological filter of your fish tank requiring frequent water changes as well as good maintenance practices.

The Porcupine Puffer Fish are not typically a threat to other fishes. However, they might nip at those species with elaborate finnage, fishes that resemble the substrate or species that could not move very fast. They do not typically bother each other, although it is best to add them to the tank all at once.

This puffer fish is a potential threat to a number of different invertebrates, consisting of worms, snails, clams, sea stars and also sea urchins. This fish is not considered reef tank safe. However, tangs, triggers and also larger wrasses would make good tank mates. Anything smaller can become puffer snacks.

 

Reproduction Of The Porcupine Puffer Fish

Reproduction Of The Porcupine Puffer Fish

The Porcupine Puffer Fish are difficult to sex. The only sure fire way to determine their gender is to make the tank match their breeding needs. When it comes to the breeding portion, it merely is not possible for the average aquarist. These fishes are simply too large for their eggs to survive in captivity. Since the moment of this writing, reproducing in the home aquarium has not been reported.

Additionally, egg scatterers that produce pelagic eggs, frequently in midwater mating rituals. Both eggs and larvae that drift with plankton in the water column as well as settle back onto a reef at about the time of metamorphosis. These are among the most difficult types of marine fishes to propagate in captivity.
