I bought 5 of these cute little things and have them in a quarantine tank. The LFS said they were platies, so I assumed very dark Bumblebees. I posted on another board and was told they look like Gold Dust Mollies. Well, they are DARTING around like crazy. I know platies are fast, but I've never seen a molly this fast. Of course, they are only babies. I can't tell which they are. I know these aren't good pics, but they are so FAST that it's very hard to photograph them. Gold Dust Mollies, or platies?
