Helfrichi Firefish and Purple Tile Dartfish Coexist?

So i know firefish and dartfish of the same species don't get along. But now that i have my helfrich, that looks like a pea in my tank, would it be possible for these two to coeexist in the same tank? I know the Purple Tile gets about 6" and the helfrichi 2 1/2"

Just trying to get opinions, i would love to have both of these fish but if not possible, it's not possible, I would just like to get opinions

 

i personally wouldnt try. the Helfrichi Firefish might just make an expensive lunch.

 

+1 - with the firefish keep fish of similar size and temperament - they get bullied too easily
