Any advice?

Here are my two tanks. The first, a 29 gallon stocked with a pearl gourami, rummy nose tetras, another type of tetra, and Pygmy corydora.

The second, a 20 gallon stocked with many shrimp, two red honey gouramis, zebra danios, guppies, Otto catfish, and green corydora.

I know that these tanks are pretty stocked, but I have a lot of experience and do tank maintenance often. If you have no stocking opinions or advice, what about the tanks would you change or add? Thank you!
