alternative for harlequin rasbora

I haven't kept swordtails in a long time- I think if you wanted to get one gourami, two swordtails and the three cories that would be okay in a ten g. However, While swordtails aren't as prolific as say guppies, they are still livebearers. Which of course means that even with the gourami acting as population control, you might end up with more swords that your tank can handle. The nice thing about egglayers like tetras and rasboras is that breeding them successfully is more of an effort. My harlequins lay eggs all of the time, but I have yet to see any offspring. You could get two males, but they might stress each other out- two females could arrive pregnant and (just in my opinion) the tetras would add more to your display in terms of activity, etc. but it's all about what appeals to you.
 
I think with a dwarf gourami, 3 cories, and 6 harlequins the tank would be fully stocked. Or, at the very least, there would not be room for a sufficient school of any other type of tetra.
 
He doesn't have any fish yet- I think he is just asking basically what could go in a ten gallon- or am I wrong on that?
 
Hmm okay. Thougt he was planning on the dwarf gourami, cories and rasboras. Because of where he said:
"i was gonna get 5-6 harlequins"

I thought you meant "in addition to." Sorry, my bad.

Alternatives to the rasboras would be neons, cardinals, ember tetras, scissortail rasboras (they do get slightly bigger than the harlequins, but I have some and I really do like them (they're in a 10g))...
 
Get the harlequins if you can, I have 4 of them in my 10 gallon and I really like them.

They're a little unusual (around here at least), colorful, and they school together very nicely.
 
I have expirienced trouble with swortails in a ten gallon, seemed to be to small for their ocasional squabbles.
Platies however are more suited as they naturally tend to inhabit slower moving areas of water and don't feel the need to exibit speed of movement.
