I'm looking for suggestions other than betta fish, shrimp and snails as i am not really interested in them.

Then, unfortunately, you'll want to start a larger tank. Really. 5.5 gallons/21 liters, depending upon dimensions, limits what you can keep. It's inhumane to keep most species in such a small volume of water.

If you plant well, you could potentially house a single Pea Puffer. But you will need to maintain cultures of live food for them and be prepared to take terrific care of your tank. Could also consider a small number of Heterandria formosa.

Some may recommend Dario dario but they really do best in a larger volume of water. Same goes for Endlers and Guppies.

If you put in some effort by going through the Tank Journals section here and using the search function, you'll be able to find a ton of journals of people with similarly-sized tanks. That could help you come up with livestock and plant ideas. Seeing actual photos is also nice.

Thank you for taking the time to reply, i appreciate it!

If you provide dimensions for your tank (Length x Width x Height), that will help a lot.

And if you have photos of your setup, that will also help others come up with recommendations and tips. There are some small bottom dwellers that could work well, depending upon dimensions.
