Would this stock work

[xfactor6699]

So I have a 40g could I do
1 male betta
6 harlequin rasborias
6 albino cory
And a pair of kribensis

If your going to do the beta fish none of those fish could work try platie swordtails mollies angelfish and a school of bala shark or white clouds also ghost shrimp do well.
1 male beta fish
3 white clouds
4 bala sharks
or you can add the others

That plan sounds fine. No fin nippers, and you shouldn't have problems with food competition unless the rasboras are REALLY hungry. Mine have been known to jump...

bala sharks get way too huge for a 40 and white clouds are schoolers. why wouldnt the others work? they seem fine to me
