Aw, man! I was hoping the one with the more translucent tentacles was something cool. I kinda figured the brown one was aptasia, but I wasn't sure. Thank you for your help!
2- using a syringe. . . inject either lemon juice or preferably kalkwasser powder mixed into a thin paste and inject into the center core of the aptasia and it will melt away
3- Siphon up and look for any others and presence of eggs. A 6- line wrasse maybe, but a lunare ot melanurus wrasse will eat these.
I will be injecting the aptasia. The flatworm I removed. The tank is still cycling (nearing the 6 week mark) so no fish are present. Clean up crew was recently added.
