“Moon Tail Molly” seems to be a term related to aquarium fish, specifically a variety of the Poecilia sphenops, commonly known as the Molly fish. Mollies are freshwater fish that belong to the Poeciliidae family, which also includes guppies and swordtails.

The term “Moon Tail Molly” likely refers to a selectively bred variation of the Molly fish that has a unique and striking tail shape, resembling the crescent moon. This tail shape is achieved through breeding and genetic selection. Mollies are popular aquarium fish due to their diverse color patterns, ease of care, and their ability to adapt to a wide range of water conditions.

It’s worth noting that the names and variations of specific fish strains can vary based on individual breeders, trends, and regional preferences.

As of my last knowledge update in September 2021, the term “Moon Tail Molly” might not have been widely recognized, so it’s possible that it has gained popularity or evolved in meaning since then. If you’re interested in learning more about this specific variation, I would recommend checking with reputable aquarium forums, fish breeders, or up-to-date resources in the aquarium hobby community.
