That sounds pretty full to me. The cory and the glass cats will take up a lot of the bioload...also you should be keeping your neons in groups of 5 or more ideally. If anything, I'd get 2 more neons but I'd also suggest upgrading your tank size if you want more fish at all (even neons).
Remember, for every 1 inch of fish you should have 1 gallon of tank. Cory cats can get up to 3 inches each depending on the type! I don't know much about glass cats tho sorry.
Best of luck!
