Is my tank to full or not full enough?

[tetra lover]

I have a 100g tank (6'x18"x19") which is planted fairly well. I have a Eheim 2216 and powerhead running it. The current occupants are:
Bottom:
3 clown loaches about 3"
1 bristlenose pleco
5 cories
Middle:
6 Gold Barbs
2 Blood Parrots
Top:
4 Angelfish about 6"

Is my tank overstocked at all? If not, is there anything else that I could add?

Thank you in advnace.

I wouldn't add anymore. A lot of those fish will get very big. The loaches will probably reach 8 inches.

I think if you up your filtration you could add alot more fish of the community nature.

I agree with scott, definitely add more filtration and you can easily add more fish. A six foot tank gives you a lot to work with. It also costs a lot to work with.;)
