Differences Between Porcupine Fish Vs Puffer Fish
The main difference between porcupine fish and puffer fish is that the former have visible spines but the latter don’t.
In the face of a threat, the puffer fish puffs up, and the spines, which are actually specialized scales, become visible.
Porcupine fish belong to the family Tetraodontidae while puffer fish belong to the family Diodontidae.
Here is a table that shows the scientific classifications of these two species:
|Genus Species||29 genera, 191 species||7 genera, 18 species|
What is Puffer Fish?
Some species of the fish are critically endangered due to habitat loss, pollution, and overfishing.
The fish inflates itself with water and air, like a balloon—to evade predators. Most puffer fish contain a toxic substance which is deadly for humans.A puffer fish can contain enough poison to kill up to 30 adult humans.
In Japan, puffer fish are a delicious treat, and pretty expensive. However, because they contain a deadly toxin, they must be prepared by licensed, trained chefs.
What is Porcupine Fish?
The porcupine fish, also known as globefish and balloonfish, belongs to the family Diodontidae, order Tetraodontiformes. It lives alone near caves, reefs and ledges, and hunts mollusks and crustaceans at night.
The porcupine fish is shy in nature, and retreats when approached by divers. The fish has a white belly.
There are spines all over its body, which are actually modified scales. When the fish is threatened, it inflates its body with water, and the spikes stand out.
This fish is considered poisonous because it secretes a highly toxic skin substance. The liver, ovaries and other internal organs of the fish contain tetrodotoxin— a neurotoxin 1200 times deadlier than cyanide.
Due to its lethal defense mechanism, the porcupine fish has very few predators.
In general, the porcupine fish is not eaten. However, some species are eaten in some places of the world. In Cebu, Philippines, the fish is an exotic delicacy locally known as tagotongan.
Can Porcupine Fish and Puffer Fish Live Together?
No! It’s not a good idea to house porcupine fish with puffer fish. Also, avoid keeping multiple porcupine fish in the same tank. This is because they often become hostile towards each other.
However, porcupine fish are not hostile towards fish of other species. Some good tank mates for porcupine fish include wrasses angels, tangs, foxfish, engineer gobies, and squirrelfish.
When choosing tank mates for your porcupine fish, make sure you avoid very tiny fish because they may fall prey to your porc. Avoid all mobile invertebrates.
When it comes to choosing tank mates for puffer fish, your choice should be based on the type of puffer fish you have.
In general, some good options are kuhli loach, otocinclus catfish, fancy guppies, tetras, danios, rasboras, cherry shrimp, and clown pleco.
Here is a table that shows the suitability of various tank mates for particular species of puffer fish:

Puffer fish are more suitable for living in an aquarium, in part because these fish are very hardy. They are mild-mannered toward other species, and become aggressive and hostile only when threatened.

Puffer fish can eat a wide range of foods: mussels or clams, frozen or fresh shrimp, flakes or brine shrimp.
For puffer fish, the tank water should be between 25 and 26 degrees Celsius. The pH should be 8.1-8.3. Also, you have to do a 25% water change every couple of weeks.
The price of a puffer fish can be anywhere between $20 and $60.
