i really dont know if its a hitchhiker or not. i was in a lfs about a month ago buying liverock and the rock came out a tank where they were selling small red anemones for $40. this polyp looks almost exactly like one of them. its looks almost exactly like my red polyps but its body structure is different it arms are four times as long as the arms on the other polyps.
Ahhhhh ok. I was looking at the wrong thing. Hm I see what you mean, it could be an anemone. Poss a red rock flower anemone? But it's hard to tell cos it's so small! It might just be a deformed zoa though..
its not the red rockflower anemone. it appears to be posing no threat to anything though so i will just leave it be until i buy some skunk cleaner shrimp.
