I definitely wouldn’t put any fish in there, no matter how small they are. It’s 2 gallons of water full. That doesn’t consider that the water isn’t filled to the rim, and that all the other stuff in there takes up space, so there’s less water because of that too.
I also can’t tell if I see a filter in there, but you definitely want a tiny sponge filter or something like that if you want to put animals in there. As long as you have a filter and properly cycle the tank (process involving adding ammonia and monitoring water tests, typically takes 4-6 weeks) 6 neocaridina shrimp would probably be a good start.

I don’t think fish would be good in this, as for shrimps I don’t know how many but I know it will be a rocking Shrimp tank!
