Only other fish are 2 cories (julii and habrosus) and 3 black phantom tetras.

In this small a tank, please do not try this. A 20g long (30 inches length) is much too small for the angelfish and the blue ram as it is [they will grow, or should, and a mature angelfish is not going to be healthy in this situation. Also, watch out for the phantoms; with only 3 in the group, they will likely be stressed in time, and this frequently results in fin nipping, and the angel is a prime target. There should be 6-7 of the phantom, that would be much better. The angel will soon need more room.
The male Bolivian Ram will come to consider any tank he is in as his
space. I speak not only from considerable research on this, but personal experience as I have kept this species for many years. I presently have a male Bolivian in my 5-foot 115g, and he rules that entire aquarium, very clearly. He never (or rarely) bothers the other fish (over 100 various tetra and corys), but if any of them get in his way at feeding, he makes his presence known. It was entertaining the other day for me to sit watching him enforcing his will on the group of Bleeding Heart Tetra, which are a decent size in themselves. They were getting too nosy over his substrate tablets, so he took matters into his own hands--or perhaps fins.
He rarely is more than 5-6 inches from the substrate, but that day he was up mid-tank, with the group of five BH all clusteredd together slightly above him. If any one of them attempted to move closer to the substrate, he would move toward it and it quickly retreated back into the shoal.
