I have two 7" chalceus. They're characteristics are different. I've looked online and there's 2 pink tail species. I'm not sure which one is which. Can anybody confirm the specie for left and right and estimated max size? Thank u.

I have one; mine looks like the one on right. I did not know there are different types. Maybe one is female and one is male? I think they get about 10 inches.
 
The other one is a yellow fin or toucan fish. Max size is listed as 8"
I want to get six of each for my top water, how do they get along with each other?
 
Which one do you like better?

I don't have a preference. Both sold as Pink Tail Chalceus. They both look physically different. Chalceus Erythurus and Macrolepidotus will show pics of both types. You'll see what I mean when browsing through the links provided below. It'd be cool to know as I want to keep these top swimmers in my Polypterus tank. I've seen some that grow up to 10 inches or more, but didn't pay too much attention in the past due to the pink color.

As for sex. According to several sites. They are very difficult to visually know.

They like to be together on the top. I have polys below. They are great dithers for the top. I tried a school of 7 Apollo sharks recently. Had to move them because had a poly grab one. So, they are growing out in another tank.

I'd like to get more Chalceus if I can find them. They grow pretty fast in my opinion when small. You can see the two pink tail from afar in the beginning of this video.
