My Freshwater aquarium.

Ok, i have 3 Neon Tetra(I believe one is male and the other 2 female), 4 Angelfish (dont know, but i hope i got at least one couple), 7 guppies(3 male and 4 females) and 2 rainbow sharks(i think they got over the fighting… i think 1 is male and the other female(albino), they live both in the sunken ship).
My tank is a 20 gal(80 liters).
Im getting some plants and rocks, need brine shrimp for my fish, by the way, i need help with the angels, they dont move alot from the ship. I love angelfish, my favorite in my tank, i would like to hear any recommendations in fish, i believe i have compatible fish(in temperature, food and other simple things).
