Hi I’ve had these Zoas for maybe 2 month now and I just recently noticed these things growing on them too as well as the number of zoas going down not sure what’s going on?

Aiptasia, they sting and irritate corals. You'll want to remove them - there are many methods out there though so I'd do some research to determine which one suites you best.

I don’t see anything in the first image except Zoa. Circled I believe I see aptaisia.

I had the same thing in a zoa frag, I used a syringe to target the aptasia with kalk paste. I’m sure there are better methods, but this worked.
