Convict fry/pair update

#1
Well i moved the convict fry into my 20gal last week. I am thinking of selling them to a lfs along with the convict pair. My plans with the 30gal is either Angel breeding or Discus breeding, and for the 20gal im thinking of moving the following fish in there to breed(one after another)

1. Keyhole cichlids
2. German Blue Rams
3. Kribs
4. Harlequin Rasbora
5. Gold Opaline Gouramis
6. Bolivian Rams
7. C. Sajica(if i can buy some)
8. Apisto sp.
9. Bn plecos

And since it is a 20gal tall, i am thinking of trying out an angel pair in there and see how they do, but i am not sure yet due to its small size. I might regret selling the Convict pair, but i am pretty sure that i am going to cause my 75G is kind of stocked and i am wanting to move some fish into the 30gal after the Angel/Discus project and some into the 55G.
