Great start, nice work. My only suggestion would be to toss in some floating plants. A few stems of some stem plants will suffice, Brazilian Pennywort if you can get it, or it not Wisteria works, as will others. This will calm the fish considerably, they all like a "roof" over them.
I had some wisteria and it really didnt fit well.. but maybe some duckweed would work? the cories are just peppered. I think i might just add a few more tetras if anything. Im leaving for college next year so i dont want to put too much effort into it. but thanks for the feedback!!
