It's good that you got a big filter for your tank. You really need to be keeping tetras in larger groups for them to do better. The same thing applies to corys.
Also, are your Platys 2m 3f? or 1m 4f? You never want more males than females. They females get harassed too much and they become unwell.
Back to the tetras. I suggest picking either glowlights or neons, and getting rid of the other kind of tetra. Get 10 at least of the one you choose If it were a smaller tank you could get 7. My vote is neons because I like they way they look better.
If you really wanted to, you could keep both kinds of tetra and get 7 of each. I just don't want you to put too many fish in there.
Try to change 25-30% of the water once a week.
You could also add another 3 corys. I'm glad you aren't grossly overstocked like most newbs are. And your fish are all highly compatible.
What are you feeding your fish right now?
If you want something different and interesting, you could add a group of (very hardy) amano shrimp. Just make sure you feed them. They do better that way than just being left to scraps and algae. There's actual shrimp food you can get online. The Amano shrimp aren't too expensive. They get pretty big, live a long time, and are interesting to watch. You could throw 10 in there no problem.
