Amano Shrimp Stocking

I have a planted 20 gallon tall tank. It's currently stocked with 3 dalmatian mollies, 2 swordtails, and 1 dwarf powder blue gourami. I added the three mollies last week and haven't seen any spike in ammonia or nitrate/nitrites, so I think my tank is handling that amount of fish very well. I was interested in getting some amano shrimp because as of right now I don't really have any bottom feeders/algae eaters and I think they're cool. But before I went to the store I wanted to ask:

1: Would any additional shrimp put me over the bioload limit for my small tank?
2: Are amano shrimp ok by themselves or in a small group?
3: Are there any stocking issues with the fish I currently have in there (i.e. will any of my fish eat them?)

Thanks

 

You should be fine. I’d do 2 amanos.
Is your tank planted? Your DG may try to eat them.

Yes it is planted, I have a few amazon swords in there

 

Pictures?

 

Amanos do well in groups, two should do well. Try to get females as they get a bit bigger. They're wonderful shrimp.
