No and no... Kind of.
It's been concluded Dino's exist in all home aquaria, it's just a matter of what strain and at what magnitude. They can be a headache to get rid of.
Looking at your photos I'm not sold on the fact it's Dino's. Could be, but I'm putting my money on calothrix.
Like I posted in your other thread, get an ID. Then your one step ahead.
