midge Posted December 20, 2007 Report Share Posted December 20, 2007 Hi, I was in the LFS today and saw some really neat mollies. However, I didnt get any as I think I read ages ago that they cross breed with some other type of fish. Is this true? And if they do cross breed is it a problem with the type of fish you end up with? I have guppies, platys and swordtails. Thanks Quote Link to comment Share on other sites More sharing options...
OscarBoy Posted December 20, 2007 Report Share Posted December 20, 2007 I am prety sure they do but not 100% sure Quote Link to comment Share on other sites More sharing options...
Dixon1990 Posted December 20, 2007 Report Share Posted December 20, 2007 There is a possibility they will breed with guppys,as they are in the smae genus i think? Quote Link to comment Share on other sites More sharing options...
midge Posted December 21, 2007 Author Report Share Posted December 21, 2007 So is it ok to have mollies and guppies in the same tank? Quote Link to comment Share on other sites More sharing options...
Caryl Posted December 22, 2007 Report Share Posted December 22, 2007 Fish like mollies, guppies, leopardfish and platys all belong to the family Poeciliidae. Mollies and guppies are both of the genus Poecilia, whereas the leopardfish is Phalloceros and the platies and swords are Xiphophorus. Some of the species are capable of interbreeding. The males of this family are well known to try and jump anything that moves - male or female! :-? Many find keeping mollies separate is better as they are larger and get the food first. They also like a bit of salt in their water (1Tbs per 10L). In fact, if the salinity is slowly increased, mollies are capable of living and breeding in sea water with a density of 1.024 - 1.028, which is the same as the coral sea.

Now thats something I did'nt know.... I guse that is why they are so hardy thn right? Quote Link to comment Share on other sites More sharing options...
Caryl Posted December 22, 2007 Report Share Posted December 22, 2007 I never found them hardy. In fact, when I kept black mollies they were always getting whitespot. That was years ago and I suspect we didn't have them in the right conditions. They live in tidal areas so their water goes from fresh to salty with the tides.

Caryl Posted December 22, 2007 Report Share Posted December 22, 2007 I don't think so actually. Possibly better quality foods with more vitamins etc. Quote Link to comment Share on other sites More sharing options...

Caryl Posted December 22, 2007 Report Share Posted December 22, 2007 Platys and sword are essentially the same fish, just different fins. Quote Link to comment Share on other sites More sharing options...
