Yea once they are saturated they should not just float at the surface .
Mine actually sink rather quickly ?
I also use a surface skimmer like the Ehiem 3750 or Aquaneat to take food from surface and shoot it through the water column.
I just remove the sponge and it works well to give floating food some mid water 'action' ..
It is true for wild blues and greens in my experience. Unsure about Heckels. I had one streamer in a wild male green. I have heard that domestic females can have streamers. I would rather other members comment on the gender differences between domestics as I do not have a lot of experience with domestics.

They are really getting big Frank, very soon they will look like tiny cichlids and soon after, little discus.

Frank, your excellent photography is making this a great learning experience for us.
I am not handy with camera and up loading things but I will try to get my son, Little Ricky, (his mother named him after the little kid on I Love Lucy) to try it for me so you can see what I am talking about. The Red Alenquer (thanks Kenny) has exceptional multiple streamer on both the top and bottom fins. He may well have been bred for that feature. I plan on breeding him for longer fins going forward. I think they do that with Angelfish? At least they used to. At the moment I do not have any female wild crosses so until Kenny gets going again so I can get some females from him I am on breeding hiatus.
This is not a confirmed male but like yours, it is from Kenny.
You will note the streamer on the top fin. I wonder if Kenny has observed the same situation.

Loving your updates. Good work Frank
