In the first photo, is this aiptasia or some other pest anemone? The tips are a bright green color

In the second photo, are these aiptasia or hydroids?

:)
 

First one is mushrooms and second one is Candy cane coral :lol:... (ok enough with my smart *** comments). First appears to be a mjeno ane. second is iether hydroids or feather dusters a little blury to tell though. BRING OUT THE PEPPERMINT SHRIMP MUAHAHA!

will the old lemon juice work on the majano?

the peppermints havent touched the aiptasia.

1. aiptasia
2. Almost looks like Zenia because of the finger-like protrusions. Any closer shots on that one?

Yes lemon juice will work on the majano, you just have to get it into the stalk. You'll know its dying or you got it if it turns bright purple.
