By I think so, I mean they really should. They're all still mollies. Just massively bred to enhance certain traits and minimize others. Or atleast thats's how i understand it.

A true sailfin molly is not the same species as one of the shortfinned varieties. Most of the fish we see in the hobby are hybrids between distinct species of molly but are usually composed of P velifera, P latipinna and P shenops (recently being renamed as P mexicana). The pet shop mollies are the hybrids of two or more of these species and often are more than wiling to mate with each other. Wild fish of those 3 species do not cross naturally, but artificial environments have been used to induce them to breed in captivity and now they are all mixed together and don't know any better. A real sailfin molly, almost unheard of in a pet shop, is a magnificent fish about 5 to 6 inches long with a dorsal fin that is about an inch tall and spreads across the fish from pointing towards his nose to almost touching his tail in the back. Have a look at this guy to get an idea of what a real sailfin looks like http://nas.er.usgs.gov/XIMAGESERVERX/2005/20051107095034.jpg

Will a Black Sailfin Molly breed with a regular black molly?
I don't know for sure about Mollies...but,the black colour can be a lethal gene if bred to another black. I've had trouble with Guppies and this problem,and this also seems so with Bettas!:shock: Does someone here know about this lethal gene in blacks? When I've bred Mollies,I've usually used 1 black,and then a black marble for the male...no probs with that! But,black with black?...just don't know with Mollies!Good Luck tho!:p

I went to a LFS today and they had a bout three sailfins that looked VERY close to the one in the picutre, they were about 3 inches long.

Well we should find out soon, one of my female mollys, is getting so fat so i beleive she is pregnant. Im not sure how long it takes for her to give birth or when i should expect it. So im going to keep an eye on here and set the breeders net up just in case.

Ok my mollies at night recently seem to be grouping up together in a row by the heater and sleep together and my mail sailfin keeps shooting up his fins chasing my females.... I have no idea what they are doin. Do any of u have any idea, they never used to group together before at night

Almost all of my tanks have fish that are sleeping in a group somewhere at night. If you sneak into the fish room and don't turn on any bright lights, there are rafts of fish in some tanks while others group near the substrate. Still others are hanging around a plant. Almost all fish find a place with relatively still water to sleep in.

There are several possibilities with a female that is hiding. Most often when that happens in my tank, she is getting ready to drop fry.
