Is This Ok?

[chuckie500]

I have a 160 litre tank that has been humming along for some time now. At the moment I have: 1 angelfish, 1 blue gourami, 1 lace gourami, 8 rummy nose tetra, 4 albino cories, 3 siamese aglae eaters, and 1 sucking catfish. I have an external filter and many plants.

I was thinking of adding a pair of ram cichlids. Is this a good idea. Am i overstocked?

Thanks
