The yellowfeen split from its ancestor. It is the result of neoteny, a process in which juveniles of one species become sexually mature while still in their juvenile form. They are twice the size of their ancestor's larva. Yellowfeen are much more opportunistic than their ancestors eating nearly anything they can swallow, including the larvae of its ancestors! However its ancestors larvae are not a main component of its diet keeping it from replacing its ancestor.
Natural selection has made the mouths of yellowfeen much larger which works well with an ingenious new reproductive system they have developed. When a male finds a suitable female it will exchange genetic information with her via their mouths. The fertilized eggs develop in their mother's mouth for a couple days before the mother coughs them up in batches of 10-20 individuals. They hatch soon after and grow to their full size in about a week and reach sexual maturity in roughly two weeks thus repeating the cycle. Other than that they are the same as their ancestors.
