These are mine. I'm not certain what type they are, I got them from Petsmart, but they seem to be one of the smaller species. I'm not certain if I have two different types or a type with noticeable difference between males and females- can anyone help me out with that?
And how do you get such good photos of such active fish? All the photos I took turned out to be blurs, which is why there's a video, and the video isn't even all that clear.
You can also see a Mexican molly (livebearer in the first few seconds) and an experimental tankmate- the angel. He's about the same size as the dollars. There was some fin-nipping at first and the angel lost his fin-tips, but I think they just wanted to see if he was edible- they've left him alone since. They tried this with the Mexican molly's orange tailtip, too, and they don't care about him any more. Evidently fins don't taste great and they'd rather eat duckweed.
