Oceanic Form
Every January, Heart Betta migrate from the rivers of the Isle of Xaaida across the ocean to the mainland of Kladeon in order to seek out a place to spawn. The fish arrive by the time of Heartsgiving to breed. At the end of Heartsgiving, they seemingly disappear as they make their journey back to Xaaida to return just in time for the first thaw in the Spring. Before migration, the fish eat plenty of food and absorb mana to change form. The bettas take on a bigger, more dangerous form, growing a uniquely shaped horn and longer whiskers, along with the large heart shaped marking on their forehead and arrow-like lines that run down their sides. All wild bettas have these features during their migration, though they retain their original colors and other patterns, along with growing to about twice their size. The Bettas become more aggressive in order to survive as they migrate across the ocean. As they reach the rivers of Xaaida, Islanders catch glimpses of the fishes' more monstrous forms as they return to the lakes they spend the rest of the year living as their usual, small forms. The cycle repeats in January again, when the fish take their oceanic forms once more to migrate back across the ocean.
