Please advice about my aquarium

Hello everyone, I'm new to the Hobby, I'm reading a lot and very excited about aquariums.
This is my aquarium, it's 80 liters, filter is Tetra 600+, light is a 36W led 168leds.
I have there 12 sorts of plants and:

12 Microrasbora Galaxy
4 Dwarf Gourami (1+3)
3 Garra Flavatra
3 Orange Venezuelan Cory
4 Cardinal Tetra Fish (Red Neon)
4 Ammano shrimps
11 Nerite Snails


I'm open for any advice with my aquarium, any tips and comments, on what to change, what to try.
And also will it be ok to add 2-4 Otocincluses or it will be overplacement already?
Thanks a lot if you read all of this ))
