I would increase the green neons to 12 so they are happier.
Most bigger colorful fish might attack the green neons.
If you get a smaller betta, it might get used to the green neons as it grows.
GBRs need warmer temps than BN plecos, so I wouldn't add those. I would also take out the BN pleco though - they get around 5" and have a heavy bioload, and a 20 gal doesn't give them much room/volume. You could rehome the pleco and get 2 GBRs then? You don't need to replace it - you are the best at preventing and controlling algae.
They might! Worth asking.
So then you could do 10-15x green neons and 2x GBR. Sounds like a great tank!
I would try larger ghost shrimp or amano shrimp just in case because they grow a bit bigger and have a less likely chance to be eaten.Thank you so much for the help! Any thoughts on shrimp or would the other fish eat them?

For feeding, NLS, Omega One, frozen foods, and homemade foods are my favorites.
Depends - are you trying to grow live plants?
If you want something cheap but made for aquariums, Finnex's Stingray or a Beamswork would be great. If you want to do DIY lighting, you could easily use two dome work lights with plant friendly bulbs (also cheap)
