so, this piece of base rock was given to me from my brother who had it sitting dry in his basement for a year. within 5 weeks something grew on it. it is right near the substrate.

aptaisia

inject it with lemond juice with a syringe

Aiptasia; it's a pest anemone. There are also fish that will eat it, namely butterfly fishes.

Can you get a clearer pic? It almost looks like a paly more than aiptasia to me from this pic? (tentacles too short) If you poke it how fast does it retract?
I am more inclined to think aip just because the little buggers are survivors but .... so are palys...

[spit.fire]

if you poke it and its aiptasia it will spread, if you get fish that eat it, it will spread, the only way to actually get rid of them is injecting them

Looks like a button polyp to me, is it green under actinics?

[STANKYfish]

+1 on the paly. Wow i did not know they would last even after being out of water so long.

[spit.fire]

If it is transparent its most likely aiptasia

I'll check colour under different lighting when it gets darker.... for now......

k, just checked now anyways.

there is a slight green tinge to its center under pure actinics.
