    So I had a dalmatian molly have 3 batches of fry.
    All seem to be half sailfin but thats impossible right? Id gotten the dalmatian molly from a LFS and have no idea what she was housed with before being in the molly tank at the store.
    - 1st batch colours are large dalmation prints with gold fleck
    - 2nd batch colours are white with yellow patterns and the same large print dalmatians, no gold fleck
    3rd batch were grey with smaller spots, white, all black, all brown, and the rest were the dalmatian print but with smaller dots. photos attatched 20171218_150556.jpg
    ^^ sailfin-ish?

    You have a beautiful fish! Well to start off, all mollies can breed with one another. There are just different versions of the physical features, known as the phenotype. As long as the species of fish is the same they can breed, and their babies will be able to breed as well. This is similar to dogs. Although, there are very diverse breeds with many appearances. Dogs are generally able to breed with one another to produce puppies, this is because dogs are all the same species.

    It seems like your mommy's traits (dalmatian print) was mixed with some other mollies she was exposed too.

    Actually, most of the domestic Molly strains are hybrids of several species of Molly. Some of the species involved are the two sailfins, Poecilia latipinna and P. velifera. Your dalmation female appears to be from one of the Sailfin lines, but only males develop sail fins. That's why the young male in the earlier photos has an enlarged dorsal. He will need a great deal more space and good food to grow out a full sail fin dorsal. There is also a theory that sunlight somehow helps with fin growth, but I suspect that is just because it encourages healthier plant growth. Dr. Joanne Norton grew males with large sails in 55 gallon tanks, no more than two dominant males per tank.

    Okay, I didn't explain that those two males in a 55 only had 3-4 females with them, and the tanks were not decorated. She also was one of the early believers in massive water changes.

    All Poeciliid livebearers are born with female finnage, males change when they reach sexual maturity.

    It appears to be a female from a Sailfin line. Not bright enough white to be a Silver variety, no other colors to mark it as other varieties, so I would just call it a female Sailfin Molly.
