I was on your side till I saw the CAE and 2 loach. I'd say you were overstocked but you do have good filtration and the shrimp and loaches will help clean up also so I think your still on the boarder. I wouldn't add to it at all.
The chinese algea eater isn't welcome in this setup.. As soon as an oppurtunity to get rid of him comes up. He's gone.. The loaches.. When they get too big I will just return them and get some smaller ones. I won't try to keep full grown loaches.
