Sick platy and molly

45 gal- Started 8 months ago
2 Dalmatian mollies
2 cream mollies
1 black molly
4 red wag platys
11 danios
6 tetras
5 neon tetras

Ammonia- 0
Nitrate- 20
Nitrite- 0
GH- 150
Chlorine- 0
KH- 180
pH- 7.8

Our tank has been great for 8 months. A few random casualties in the beginning but very stable for quite awhile. We do 30% water changes every 2-3 weeks. I add calcium to make our mollies happy and we are careful when changing filter media (aware to tank cycling etc). Two weeks ago a red wag platy (no longer with us) started looking like its scales were falling off or losing color. Then it had a crazy spine distortion (looked like an upside down "u" from the side. After a week he died. All the other fish looked normal so we thought it was random. About 5 days later a danio (one of our starter fish) with no symptoms died. I started to worry and test daily. Water continues to be the same. Now I notice the cream mollies are turning lighter. I'm pretty sure losing scales but acting normal. One of the Dalmatian mollies has a bulging eye but acting normal. Behavior wise they are all normal. Nobody is rubbing on hard surfaces and all are swimming/ eating well. I have noticed a non sick molly has been pestering the other Dalmatian molly more than usual but not to extreme. Also, we had mollies with a bulging eye early on but the calcium fixed it. I'm not sure what to do and most "research" I try to do ends up with everyone contradicting each other. Any ideas?? Help would be much appreciated!

I'm sorry I can't help more with the illness, but the easiest comment is that's probably not enough water changes. Though the water parameters are ok there are aspects that don't show on a test, that clean water provides.

Are those nitrate readings just after a water change or before.
