Betta Fish: New betta keeper here 👋🏼

Any tips on how to improve my setup? I have 1 algae eater with the betta and they have been getting along so far. I also have 1 shrimp in there somewhere to see if my betta wont harass it 😅 Im hoping to add a few more shrimp too. I have a terracotta pot on the way to add in for his hide.
