Aquariums: First tank ever with my 9yo son!

My son has been obsesed with habitat making videos for a couple of years, and now that he is a little bit older we decided that it was time to sit down and plan his very first aquarium.
He did most of the research and gave me a list of things that he needed to set up a 60l tank with small freshwater school fish and some shrimp and snails with live plants.
I double check his reasearch and with the help of youtube videos and reddit post post we set his very first tank and I must say we are both loving it so far!

This is what it looks like as of today almost 3 weeks after we put our first fish in it.
Sopiler alert one of the bumblebee platys we got had some little surprises for us as you will see in the pictures.

Any suggestions or tips on what to improve to make our fish happier are very much welcome.

Right now we have:
6 corydora (3 bronce 2 panda and a schwartzi)
2 bumblebee platy and 8 to 10 fry
6 shrimp
Some snails that came with the plants.

Cheers from Montevideo, Uruguay!
