Therestarfish with red hornsit's aaquarium starfishvery appreciated. Here is how to provide for its care in the aquarium and all the information on the species Protoreaster linckii(starfish with red horns). From the board to the power supply. How to prevent starfish from dying.

Betweenaquarium starfish, the red starfish is certainly the most common, more difficult to find and maintain in the aquarium are the blue starfish and starfish with red horns.

Thestarfishthey are not easy to maintain in the aquarium, therefore an intermediate level of experience is always required or in any case it is advisable to introduce themstarfishin well established and mature tanks.

Red-horned starfish: Protoreaster linckii

Its scientific name isProtoreaster linckii, commonly known asstarfish with red hornsfor its characteristic purple protuberances (red tubercles).

In nature it can reach the size of 30 cm in diameter. It has numeroustubercles which, due to their shape and color, give the common name to the species (starfish with red horns). The tubercles are located on its five arms. THEtuberclesthey are bright red in color and extend upwards.

Due to its characteristic shape, thestarfish with red hornsit is the most commercialized even outside the aquarium trade. The trade instarfish skeletonsis a very common fact and the red horned starfish skeleton is the best selling one! The starfish is dried and then marketed without having undergone any treatment for its conservation.

Starfish with red horns: card

Origins: Western Pacific Ocean, very widespread

Dimensions: it reaches a diameter of 30 cm and is therefore suitable only for very large aquariums.

Natural habitat: lagoons, sandy bottoms, muddy bottoms, seaweed beds, coral reefs… In nature, it adapts to different depths and different light conditions, so much so that it can be found at a depth of up to 100 meters!

Diet: carnovora

Supply: in nature it feeds on anemones, soft corals, sponges, small invertebrates and benthic fauna. For this reason its introduction in the reef aquarium is not recommended.

Because of its size and also its owntubercles, in captivity it requires a very large aquarium that has one rocky area and one sandy one, easily navigable.

As for its maintenance in the tank, there is probably no aquarium made at a hobby level that is able to satisfy - of course - its nutritional needs. For this reason it is important to provide thestarfish with red hornsa specific diet.

How? By thickening the benthic fauna and providing the starfish with small invertebrates to feed on to rest on the sandy bottom.

These starfish are active during the day, if kept healthy they are able to intercept - thanks to the nerve endings located on the individual arms - the food and quickly rush over and then devour it.

Unfortunately, given the scarcity of food found in the tank, this starfish, if not fed specifically, is likely to last a short time because it practically dies of hunger.

Like allstarfish, also the speciesProtoreaster linckiiit suffers greatly from sudden changes in salinity. An osmoregulator in sump is recommended or pay attention when refilling with osmosis water. It is equally important to monitor the salinity parameters in the water.

Take this information into account even at the time of acclimatization. You can use a refractometer to check the salinity of the water of the shopkeeper who sold you the star, so as to perform perfect acclimatization. Acclimatization times should never be less than 20 - 30 minutes, gradually adding water to its bag at intervals of 5 minutes before releasing the red-horned starfish in the aquarium.

If you don't have a refractometer, a good, cheap and fairly accurate device, you can buy it on Amazon at a price of 23.90 euros, you can find more information on the page dedicated to “the refractometer on Amazon“. Consider that the ideal parameters ofsalinityfor starfish they are between 1.023 and 1.025 but there should be no oscillations.

The ideal temperature is between 22 and 28 ° C, no invertebrates like thermal shock, but the starfish are particularly sensitive to changes in salinity.
