Pest nems?

I think the brown one is a majano but not sure about the white one.

Neither look like Majano or Aptasia IMO. The white one looks like a bleached out bubbletip

The rock came with 2 legit BTA's on it, but from a system that also had a majano problem so I figured the top one had to be a majano. As for the white one, I thought the foot seemed way too long to be a BTA given how small the head is, but I'm no expert.

Any other opinions?

I was going to let them grow regardless just for kicks. I'm not adding that rock to my system, it'll stay where it is for a fun critter tank. There are some asterina stars, bristle worms and a bunch of brittle stars as well in there.

Majano def top one....let the bleached one grow out. Could be a bubbletip.
