I know there are a lot of fish that will adjust to different water types.  Right now I have a planted 45g at 76 degrees O, O, 40  PH 6.5  This tank will again be a Discus tank when I get the money up for the fish and my tank is well established. I had a big crash had to start the whole tank over.  Could a pair of Molly's adjust to the 82 degrees with a Ph of 6.5.  I will be doing this with fish I have used before in my Discus tank but have never had Molly's.  The white molly's really stand out in a tank.  Everybody will be moved into my 67g by mid summer.  What is your opinion of this adjustment for a couple of molly's?

Distribution

Poecilia sphenops
Central America, from Mexico to Columbia.
Poecilia latipinna
Southeastern North America. From the Carolinas through the Gulf Coast to Southern Mexico.
Poecilia velifera
Southern Mexico


General Body Form
Poecilia sphenops
Elongated, with the males slender and the females with a very round belly profile. Males can reach a length of three inches and the Females almost five.
Poecilia latipinna
Moderately elongated, with strong lateral compression. The outstanding feature of this fish is the Dorsal fin of the male, which he can extend out like a sail. Males can reach a length of three and three quarters inches and the females about one inch more. They tend to be smaller in the home aquaria.
Poecilia velifera
Very similar to P latipinna, with the major difference being the markings on the Dorsal fin in P velifera they small,round light spots while in P latipinna they are dark and rectangular. Males can reach a length of six inches and the females even larger.


Coloration
Poecilia sphenops
Several subspecies and color varieties are known. The best known is the "classic" Black Molly where the back is usually Olive Brown and the sides may be silvery with a Green or Blue luster marked with a series of brown or Orange dots. The Popular Lyretail varieties also belong to this species
Poecilia latipinna
The males upperside is a dark Greenish Brown changing on the sides to a blue luster with whitish markings on the throat and belly. The sides are marked with a series of stripes or bars that are made up of Red, Green or Blue dots and there can also be a few Black bars near the belly. The Dorsal fins light Blue with Black-Blue spots and streaks with the upper margin being Orange. The Caudal fin is also Orange-red with dots much like the dorsal fin. The female is very similar to the male but with less vibrant colors. This species has many varieties with different coloration's.
Poecilia velifera
This is one of the most beautiful livebearers you will see. The sides are Blue-Green with iridescent greenish, Silver or pale Blue dots. Between the dots are dark Blue to Copper color bands that extend all the way to the Caudal fin. The Belly and throat area is also Bluish, Green or Orange. The Dorsal and Caudal fins are marked with Pearly dots and are edged in Orange, Brown or Black. The female is very similar to the male but with less vibrant colors


Maintenance
Poecilia sphenops
An easily cared for fish that does well in all types of community aquaria. Give them a fairly large tank with live plants and open swimming areas, avoid too much driftwood as a rule the livebearers do not like acidic water. Although not a schooling fish they benefit by being kept with a large number of their own kind. Temperature range from sixty-eight to seventy-seven degrees.
Poecilia latipinna

Poecilia velifera
these pretty fish are best kept alone or with other Livebearers in large well planted aquariums. They prefer a little sea salt in their water (one teaspoon to two gallons of water). In addition to live and flake food their diet should be supplemented with some plant material. The males large fins depend on the nutrients from the plant food and may not develop properly if they are not received. These are a temperate zone fish and can tolerate fairly low water temperatures, but they do prefer the range of 75 to 82 degrees f.


Biotope
Poecilia sphenops
Wild form in fresh and Brackish water, especially in rivers from Venezuela to Mexico.
Poecilia latipinna
Fresh and Brackish water, in rivers from South Carolina to Mexico.
Poecilia velifera
Coastal areas in Yucatan, Mexico.


Breeding
As the male matures the Anal fin develops into a structure for reproduction called the Gonopodium. The Gonopodium can be moved in almost any direction and stores the sperm in packs called spermatophores. Once the sperm is inserted into the female it fertilizers her eggs and the rest is stored in the Oviduct walls for later use. The eggs are very rich in yolk and the young develop by consuming their yolk stores. In light colored females pregnancy can be recognized by the growing dark body marking in front of the Anal fin. Young Live-bearers are fairly large at birth and their development is very advanced. They can swim right away, which is needed to avoid their enemies including their parents who give no natal care whatsoever. The fry grow very rapidly and will eagerly accept fine flake food. The number of fry is variable due to the size differences in the species, but in larger females can number well over one hundred.

Thanks for the quick reply!

I see that Poecilia velifera live in a bit higher temp but with all the cross breeding that has occured with this breed I don't think I could be sure of getting the right fish.  It looks like they might live with my Ph.  Do you think the f?ish in the LFS would adapt
