Red Platy Variations?

So, I've been in Asia on extended assignment for a little over a year, and I recently got back into fishkeeping while I was here after over 15 years since last having fish. It's amazing how inexpensive and plentiful fish are here compared to back in the US. The fish are sometimes 10x more expensive in the US, and within a 5 mile radius of my house, there's more LFS's than I could visit in a day (I can think of at least 28 LFS's just off the top of my head). Selling fish in huge chain stores hasn't caught on here yet, which is probably a good thing.

Anyway, onto the original question. So, I've been to all of these 28 or so LFS's, looking for Red Platies.

It seems that there are several fish by different names, but they all look like variations of Red Platies. Literally translated into English, the names for these fish are "Red Ball", "Red Bean", and "Red Teapot". The only noticeable difference is that on the Red Teapot, the belly is really round on both males and females, kind of like a Ballon Molly. I really can't tell the difference between Red Ball and Red Bean. The Red Teapots cost considerably more, about 3-4x of the other two, and usually are a lot larger as well.

So, how many different variations of Red Platy actually exist and can be commonly found at LFS's? Any distinguishing characteristics?

Cool site, but I think the information you mentioned isn't on the website. I asked around at several of the LFS, and the answer that most of the shops agreed on are that Red Bean and Red Ball are basically the same thing, but depends on what the breeder/fish farm wanted to call them.
