I'd rethink the clowns. They do get big, and that's a quite a few of them. I'd cut it down to 2 or 3, and mix in some other loaches as well, if you want loaches. They all get along. Might even think of maybe 1 red tail shark or a rainbow shark if you want to give it a little bit of an agressive look. And as for angels, if you have another tank around, I'd get 3, and if 2 pair off, move the 3rd to the other tank or give back to the lfs
. It's cheaper than trying to buy a mated pair. They tent to be more expensive as a mated pair than singles. I'm still deciding if I want 3 or 5 angels for my 75G. Still leaning towards 5. Will see what the breeder says when I talk to him and order. I'm going direct through a breeder for my angels.
When well established, can look into Rams too. Bolivians or German Blues. I think I'm addicted, lol
Could also do a school of Serpae Tetras to fill out the tank as well.
