It doesn't look like NTD to me, but your rasbora is ill with something...I'm going to guess a bacterial infection just because it's fairly common; maybe columnaris but not like I've seen. I don't have any experience with a fish presenting those signs, I'm sorry.
Hopefully some will have a better idea & chime in soon.
I'm sorry about your rasboras, hopefully nothing contagious.
How long are your lights on now? Like I said (somewhere) before, some leaf loss is normal. But if you lights are on more than 6 or 7 hours, cut back a bit more. It could be diatoms too, a brown algae coating in new tanks. The new growth looks good, you may just have to wait it out. I even see a couple new sags & maybe a new crypt too. Patience!
