Enthusiastic "Re-Beginner"
I'd be hard pressed to decide whether a cherry barb or a harlequin rasbora would be the bigger bioload if you compared the two. They almost seem like they might be close to identical in body mass but maybe there's someone who's had both at the same time and could comment futher (so you could possibly go for whichever would end up being less overall biomass with 6 fish.)
They are very different fish from each other. The rasboras of course behave just like a shoaling tetra, they hang together and appreciate each addition to their group. When the shoal feels threatened they will move into a tighter school. Barbs, including cherries I think (I've had Rosy barbs and I think some others, but not Cherry barbs) will hang together to an extent but in a very different fashion than harlequins and not as much. I think the cherries will swim about with a more medium feel, whereas harlequins, in the manner of tetras, will shoal slowly but then dart with amazing speed.
The colors are differnt of course. Cherry barbs can look like a deep red little spot in the plants when you look at your tank from across the room. Harlequins are quite noted for their unique coloration. Its a combination of pink and orange that changes with the angle of the scales and makes one think of sunsets. Harlequin's color can vary, getting very deep and colorful if they are mature enough and if they are happy and healthy (probably true of cherry barbs too, although a deeper ruby color as opposed to the sunset colors of harlequins.)
