This is like a badly written comedy sketch right here....
Mr Yellow Shoes, quite frankly I think you've been more than polite and I can only commend your patience. It's not easy being new, you don't know whether what you've been told (previously) is entirely accurate, you always second guess yourself and unfortunately there is a lot of conflicting information to add to the confusion. Stick with it bud, it's not rocket science but there is a lot to learn (depending on how far you want to go with your knowledge) so time and patience are key, as is the importance of question asking.
Sick-lid-4-life, if you really have such a problem with helping someone who is obviously new/confused then I have to ask why you even bother... He didn't ask for your help,
you offered it and then start taking the piss when your short and blunt one liners don't answer any questions for him, for someone new to the scene and a specific species who is trying to find out information, you cannot expect them to know anything and everything and/or to be entirely confident in their knowledge. If they were they wouldn't be asking for help now would they....
You say "go do research", why don't you point out some useful sites for the OP to utilize then - or is he/she supposed to automatically know where to get accurate and detailed information, google is ok, but it's not very refined.
If you want to help, then help, if you don't have the patience and want to be intolerant and rude because someone is a little confused/new and that irritates you, then leave them to it, there are plenty of us here who are happy to offer help and guidance, no matter how "clueless" the OP may seem (don't worry OP this is a generic statement not directed at you.)
Mollies are of the genus
Poecilia, Swordtails fall under
Xiphophorus, as do Platys, although Platys originally fell under the genus,
Platypoecilus.... End of.
