I remember setting up my first tank more than 15 years ago. It was small I think a little over ten gallons and I did all plastic plants and decor. I ended up hating this hobby and giving up after a few months because the battle with algae was unreal. I would clean the glass in the morning and by the time I got home from work the glass would be green again. The plants would need scrubbed every few days or they were gross looking with the algae that grew on them.
Several years later I moved to a City with a big aquarium store and discovered live plants and fell in love with this stuff right away. Plants use up the nutrients and starve the algae so I never had any more trouble with algae after that. Some still grows and a little is healthy but it never took over. I like the look of your tank but i would definitely get some live plants in there. You don’t need to get rid of all the fake stuff just keep the ones you really like and replace the others with some easy plants like swords, Java fern and anubais and maybe some sprite.
I agree with everything that has been said about fish stocking but look into endler’s livebearers too and cherry shrimp. Loads of fun.
