I think you could happily plant that tank up for some small shrimp, amano, crystals tiger, bumblebee etc...all is not lost for the tank, it will require daily maintenance, much more than a larger tank, i would suggest a decent hang on filter, and a minimum of 25% water changes daily using a water conditioner + tests etc, I have 6 cherry red shrimp doing very well in a 4l tank, have a look at my nano in my sig, I have just added a picture of one of the shrimp, (should have a few more fairly soon by the looks of things) and they seem fairly easy to breed, which is a imo a fascinating part of the hobby.
Good luck
