Sudden tank mate mayhem!

HI all, complete newbie here. I'm trying to learn all I can and have already learned SO much in the past 5 months that I've had my aquarium. However, I keep running into issues... Now I feel like I've caused my happy little tank to run amok.

About my tank:
I have a 60 gallon well established tank with good water parameters: 0 ammonia/nitrite, <10 nitrate, pH 7, 50% weekly water changes.

My fish:
I currently have an albino rainbow shark, dwarf gourami, high fin pleco, spotted leaf fish, german blue ram, 2 small angels, 2 types of rainbowfish, and (what I think is) a long fin rosy barb.

The issue:
The 2 rainbowfish and rosy barb are new. I introduced them 2 days ago. All was fine for a few hours, but now my blue ram won't leave the rosy barb alone to save his life. He is constantly harassing him, chasing and nipping at him, and has suddenly started attacking other random tank mates that he's always been fine with. The blue ram and spotted leaf fish are the second newest, introduced at the same time probably 2 months ago. The rosy barb doesn't really seem to care as he's extremely active anyway, but the ram is stressing my angels and my rainbow shark out significantly. Rainbow shark has been hiding (very unlike him) and my angels are looking pretty pale and also hiding. I see him dart around the tank and nip at whatever is around him at the time, but sticks to the rosy barb like glue. He's never been aggressive before I introduced new fish to the tank. Is my tank overstocked? Do you think he will eventually get better? I'm really upset as everything was perfect 2 days ago!

I'm not familiar with Rams personally but know they can be quite aggressive.
TexasDomer is astonishingly good with stocking issues though so I'll throw a tag out for you. Good luck!

You do have some stocking issues, if you'd like to discuss them

Yes! Please!

Rainbowfish and rosy barbs need to be in groups of 6+ of their own species.

Rosy barbs, rainbow shark, and possibly the rainbowfish (depending on species) aren't temp compatible with angelfish and blue ram.

Can you include pics of the rainbowfish?

What's the L number of the pleco?

I would pick either warm water stocking (GBR and angel) or cool water stocking (barb and rainbow shark), and stock around them.
