THEscorpion fishthey stand out for a series of splendid dorsal and pectoral fins. In nature, thescorpion fishis a solitary creature and, even in aquarium, a single element must be added.
The species ofscorpion fishthat are found on the market to be adapted for maintenance in the aquarium are:
- Dendrochirus zebra, zebra scorpion fish, native to many areas of the Pacific Ocean.
- Parteroid heterurus,black scorpion fish, originally from Southern Africa and Southern Japan. It is rarer.

Scorpion fish in the aquarium
Thescorpion fish in the aquariumit does not need special care: it is a fish that adapts to different water conditions but is very demanding in terms of food (see paragraph on nutrition).
In the aquarium, thescorpion fishit needs space to swim but above all rocky caves where it can shelter. In nature, iscorpion fishthey spend a lot of time in caves and ravines, they have nocturnal habits: they feed at night.
Inaquariummust be maintained with a minimum of water movement: in nature thescorpion fishit lives in areas with minimal currents and very gentle and slow water movements. For this reason it can be kept in a reef aquarium in the presence of soft corals and hard corals lps.
Scorpion fish: nutrition
In nature, thescorpion fishit feeds on small fish and crustaceans, has a wide mouth and eats anything they can bite! For this reason, in the aquarium, it should be observed well and should be placed with medium-large fish: it could feed on small fish.
Absolutely his supply it doesn't have to be based on freeze-dried food alone. In its diet, sea shrimps (defrosted or freshly prepared) and other types of fish meat must not be missing in order to provide important fatty acids. Someone recommends feeding thescorpion fishwithRed fishesor smallfreshwater fishlike Molly or Guppy. The problem is that freshwater fish do not provide important fatty acids and other essential nutrients for the well-being ofscorpion fish. For this reason, live freshwater fish should be given occasionally and not be part of the ordinary diet. Furthermore, you must remember that freshwater fish only live a few minutes in sea water. An excess of freshwater fish can cause liver problemsscorpion fish.
Clams and preparations based on crustaceans and other live marine fish can also be administered. For artificial foods, it is possible to let them float on the surface of the tank but if the scorpion fish is very shy, I suggest you use a food spy to stick the food and place it on the bottom of the aquarium, castrated between rocks.
Among live foods, you can try feeding small crabs (such as fiddler crab) and live shrimp (glass shrimp).
Scorpion fish: sting
Thescorpion fishis popular for hispoison: have two glands containing a neurotoxin. When thescorpion fishhe feels unsafe is able to leap forward with quick movements and inject the poison by means of the cusp fins. This can happen in any case, be it another fish or the hand of the one who feeds it when kept inaquarium!
The severity of thestingit depends on individual sensitivity. Some may report very acute pain and others only complain of discomfort. In some cases, anaphylactic shock may occur (in predisposed individuals). In case of an extreme reaction it is strongly advised to go to the emergency room.
What to do in case of a scorpion fish sting?
If no extreme reaction has occurred, immerse the affected part in warm water. Hot water will help deactivate the toxin and reduce pain.
