Dwarf coral sunset platys?

i have these ans have had for a while the femalesless than 2 inches, at least the ones i bought the males smaller but the females are prone to balloon out when bearing for a while, just get really big, not pine coneing, just really big and then die mine don't seem to have very many fry maybe 2-10 at the most and i feed good..

i love them but i think they would be happier without the males..
 
i wouldn't pay too much attention to the latin names on the tags, just like the information. anything with the name platy is going to have to same latin name and it can easily be the wrong one.

Well I agree with you that all platys seem to have the same scientific name, because the are the same fish, they are just bred for a color variation. The one point I disagree about is that the scientific name is unimportant. You can have the same common name for several different animals but only one scientific name.

So it seems that Petsmart is the one out there pushing these fish. So I guess this is a fish that was either bred with smaller platys or stunted. For those out there that has these, do they seem to have a normal life span?
 
We saw them at a Petsmart here months ago and my wife/daughter demanded we get 3. They had a 10gallon for the first month+ and have had free reign in our 36 gallon bowfront since then. They've stayed <1.5", and have had no issues, aside from sometimes freaking our cories out by trying to steal their algae wafers... the dwarf platies are just as piggish as regular sized platies. The concensus opinion I found was that they weren't stunted, just bred to be smaller. Either way, we've had no issues with ours, through nitrites and ich they've been fine.
There you are then. It's still stunted. People can do everything to make variations, shortbodied, dyed, "dwarf", etc.
 
According the a person on this forum

http://www.myfishtank.net/forum/freshwater-beginner-information-questions/22773-dwarf-platies.html

"We sell those at the store I work at too. Its called a Coral Platy. It has been modified to throw a spine on an angle similar to a balloon molly, and thus has the same number of vertebra but in a smaller fish.

They seem to live just as long and arent unhealthy. They reach 2"

Be aware that a NORMAL platy can easily reach atleast three inches, given clean water, good food, and lots of space."
 
I think stunted implies connotations of poor tanks space, poor water quality, etc.

Is a toy poodle stunted? No - simply line bred for small size because within every population you will find outliers that if bred together will create larger and smaller specimens of a species at a higher rate over time. It's simple genetics not stunting.

You couldn't create a marketable fish simply by stunting otherwise normal sized fish.
