How to feed the Necklace starfish?
It's the black spot of its maintenance. Feeding this starfish is extremely difficult and very specialized: it feeds exclusively on red sponges that it encounters along the way. Most of the specimens sold for aquariums die of starvation within a year of capture due to lack of proper care. This species should therefore be avoided in most cases!
What kind of behavior does the Necklace starfish have?
Although they get along well with their fellow creatures, they are solitary. They are quite active at night and remain hidden in the background during the day.
Who can live with the Necklace starfish?
Do not introduce too many starfish into a reef aquarium. Indeed, the repeated passage of several individuals over the corals can damage them. So you can keep several specimens from 400 L / 88 Imp Gal / 106 US Gal upwards, at a rate of one individual for every additional 50 L / 11 Imp Gal / 13 US gal.
Beware of cohabitation with its predators: harlequin shrimp (Hymenocera), crabs of the genus Mithrax or Stenorhynchus, worms of the type Eunice and Polychetes.
How to breed the Necklace starfish?
Sexual reproduction of this species is very rare in aquariums.
Which aquarium for the Necklace starfish?
The Necklace starfish can be found in all marine aquariums. It will be able to live in a reef tank with rocks, algae and corals. All types of substrate are suitable.
It is imperative that it be introduced into very stable aquariums and matured for a while.

It is a very fragile species, sensitive to variations in water parameters and very difficult to feed properly. For this reason, its maintenance in aquariums should only be attempted by experts in marine aquariophiles. For all the others, it is necessary to make the mourning of its maintenance in captivity because the fight is lost in advance!
Because of its fragility, acclimatization must be extremely gentle, with a drip. Likewise, avoid buying your starfish on the internet because it does not tolerate transport very well.
This starfish has more than one trick up its sleeve! In some cases, thanks to its very impressive regenerative properties, a new individual can be born from a severed arm! On the other hand, in a domestic aquarium, this operation is very risky.
Like all invertebrates, Fromia is very sensitive to copper, which is toxic to it. Be very careful if you have to administer medical treatments based on medication!
Never take your starfish out of the water! It can swallow air, which will be fatal.
Beware of confusion with Fromia monilis, Fromia nodosa, Fromia indica and Celerina heffernani.
