What to do with a 20L and 10 gallon tank?

I've these two tanks just sitting around in my attic and I can't decide what to do with them. Any ideas?

10g tank do red cherry shrimp, crystal shrimp, and blue ramshorns in a low light planted tank.

20L do a colony of multis, AKA shell dwellers.

+1 on the shrimps. They are very fascinating and easy to breed. Also looks great!

Neon tetras and betta in the 10 gallon. I would do this for the 10 gallon.

I would do shell dwellers in the 20long - they look so fascinating!

And if you are lucky you could do the shrimps and snails AND a Betta in the 10. If you are unlucky you could have one chubby Betta and no shrimps.
