The Mahabharata/Book 1: Adi Parva…
“ From the stomach of that fish came out a male and a female child of human form. The fishermen wondered much, and wending unto king Uparichara (for they were his subjects) told him all. They said, 'O king, these two beings of human shape have been found in the body of a fish!' The male child amongst the two was taken by Uparichara. That child afterwards became the virtuous and truthful monarch Matsya."After the birth of the twins, the Apsara herself became freed from her curse. ”
