4 Chili Rasboras and Ember Tetras in 5.5 gal?

[Honem]

I have 4 Chili Rasboras in a 5.5 gallon tank. I know that's too little for a schooling fish, and I used to have more, but they died (I know what the causes were and fixed the problem). I have been looking for more Chilis, but I can't find them anywhere within a 40 mile radius. I know this is iffy, but could I potentially add some Ember Tetras to make them a little more comfortable? I heard you could add up to 8 Chili Rasboras in a 5 gal with good water quality, so I was hoping maybe 4 Chilis and 3-4 Embers? I'm almost sure the Chilis would school with them, but I'm not sure about the Embers, I've never had them before. The Chilis aren't getting any bigger than the size of my finger nail, and I feel have less biowaste than a shrimp.

Or, I could just leave them as it is. The tank is semi-densely planted with lots of hiding places, but I'm still not so sure.

I would wait until a fish store sells them. The chilis would probably school with the embers, but they would be happier if it was their own kind.
