5 gallon tall

I have a perfect 5 gallon tall that has been cycling for about 2 months now. Plants off the top of my head is a young tiger lotus, jungle val and anubius. That's just three of my stock pile.

I think its finally time to stock it other then my adult mystery snail. Im not looking for a betta, to much trauma with dropsy. I've done shrimp a few times. Love them, but im looking for something a little new.

Im looking for suggestions and maybe some experts on fresh water pom pom crabs. There adorable and if my set up is good for them, I'll hope on them. But I want a second or third opinion.

Thank you!
