What species of fish is this!?

[JesseDavidson]

I have two of these in my pond (given to me by a family friend who didn't know what they are either) and I really need to know what they are.
Thank you, Jesse.

They look like Melotaenia fluvialatillis (the Murry River Rainbow) or one of their sister species.

Ah this is Aus! Definitely a rainbow I think

(Silly me tried looking at American natives)

Oh sorry hahah should've mentioned that im in Australia. Although it wasn't caught, it was purchased from a pet store I believe

Hmm just looked it up, and I don't think they are a species of rainbow, they don't have the right body shape to me. And also they don't always have that blue shine, it only shines blue in certain light.

Looks more like a danio or minnow now that you mention it.

Yeah that's what I was thinking

I keep M. Fluvialatlis, and they don't look like this, this fish's belly is too thick, mine don't have that bulge in the back, and it's caudal fin is rounded while mine have pointed tips, also mine aren't so blue, but I know better than to argue with duanes
Every rainbow I've ever had only showed color when it was happy and the light hit it the right way. I don't think they have color, they're just iridescent. If it has 2 large dorsal fins it is either a rainbow or a danio, minnows only have one, and characins have that tiny adipose fin. I think it's a rainbow, even though I only see one dorsal fin.
