According to Miss Faragonda in "Return to Alfea", the Sirenix power is an ancient power that was born of the magic of the ocean and it will make the Winx more powerful underwater since their Believix power is less effective under the sea. She also mentioned that no one had acquired Sirenix for a long time and that Daphne was the last fairy who had acquired it and that she was the only one who knew where the ancient Sirenix Book is hidden.
When Bloom asked Daphne about the location of the Sirenix Book, Daphne told her not to look for it because when the Ancestral Witches attacked Domino, she acquired Sirenix and was ready to fight them by using it, but the Witches had placed an evil spell on Sirenix and when Daphne tried to use Sirenix it turned against herself and caused her to become a spirit without a body. Bloom ended by persuading Daphne, who reveals that the Sirenix Book is in the Magic Archives of Alfea.
The Source of the Sirenix power is found in the cave where Daphne dwells in Lake Roccaluce which grants Sirenix powers to Fairies who have completed the Sirenix Quest. It also protects the Sirenix powers of Sirenix fairies.
The hair mostly stay in ponytail, with highlight streaks and the hair changes its colors when they go underwater. Their outfits consists of a sparkly mermaid skin top, a belt, mermaid skinned colorful leggings with fins and boots with ribbons wrapped around them. The girls also wear bands made of a piece of jewelry, flower or marine creatures and strips of cloth wound around their arms, and a piece of jewelry in their hair. The wings are colorful and in seashell-shaped. Like the previous fairy powers, whenever the fairies flutter their wings, the water bubbles will be formed with their theme colors.
The outfits consists of a body suits that is less revealing and darker than Sirenix, a pairs of stiletto with fins, a glove made of the same material with the outfit cover a hand and even the socks covering the girls' legs. They wear smeared makeup on there eyes and lips. The hair mostly stays in ponytail or pigtails. Instead of seashell-shaped wings, they gain tentacles.
RequirementsThe fairies need to find the Gem of Self-Confidence, Empathy and Courage within one lunar cycle in the oceans that are all over the magic dimension, or they would lose their powers forever. After that, they needed to activate the source of Sirenix in Lake Roccaluce. Then the fairies' Sirenix boxes will appear along with their Sirenix Guardians, who combine their powers to open the portal to the Infinite Ocean. Finally, Omnia, the Supreme Guardian of Sirenix will appear with the portal to the Infinite Ocean which the fairies needed to cross into and they became Sirenix fairies.
The Witches cannot be allowed to acquire Sirenix by the Sirenix Quest, as the Trix, the only Witches known to have acquired Sirenix, obtained it after Tritannus stole it from Daphne, a Sirenix Fairy, and gave it to them.
After Tritannus forced Daphne to tell him where the source of Sirenix power was, Tritannus headed to Lake Roccaluce to destroy the Source of Sirenix permanently, so Daphne cannot protect her Sirenix from being stolen by him. After he destroyed the source (which was later restored by the Winx using their Harmonix powers and the powers of the Selkies), Tritannus absorbed Daphne's Sirenix powers and used his trident to give a dark version of Sirenix to the Trix. It is unknown how the Trix still keep their Dark Sirenix even Tritannus loses his power and trident.
“With every twist and turn, deeper you go until the Shimmering Shells sing with the ocean's voice.”
“Venture where the dark depth of the ocean shine, a precious gem self-confidence lies in the deeps.”
“Like a shining ruby under the sea, corals are strings that you feel in a key.”
“The Winx had to understand the message in the Ruby Reef's music. It leads them to Data Bridge Castle in which Aisha, Bloom and Tecna have unity.”
“Find the Flowers of the Depths. It only answers to courage.”
“Find the Yellow Reef and snatch courage from its jaws.”
Just like each Fairy has a special Believix power, now they each have a special spell/attack that they must master: during the course the will each have a special task which this power is needed although some are attacks other are abilities that use powers that are not meant for attacks but rather for purifying such as Musa's spell which was used to turn the singing whales back to their pure form.

Sirenix was cursed by the Ancestral Witches when Daphne acquired it, and it caused the Sirenix power to turn against Daphne herself when she tried using it to defend herself from the Witches. It is also revealed that Politea was also cursed by the ancient witches, and her Sirenix power became evil. The Sirenix Curse could punish the possessor physically. And as Tritannus was always attacked by the Emperor's Throne, it was clearly stated by Daphne that it is the effect of the Sirenix Curse. Later, by using Sirenix wish, Bloom breaks the curse put on Sirenix.
