So I have a full SW tank, 1.025, with snails, hermit crabs, a dottyback and my 2" GSP, who doesn't bother any of the inverts for some reason.

(I had a much larger GSP who needed the salt, but he died when we had a power outage and I didnt see any reason to back down the salinity when the smaller gsp was doing so well )

Anyways, I just noticed what I believe to be asptasia or glass anemone on one my silk plants! Now since I have no live rock, coral, or lighting to support anything like that, I was just a tad surprised I assume it came in on the back of a snail or something.

I researched (thank you WWM!) them and found they are considered pests to reef tanks, but I dont have a reef biotope, just fish and artificial plants and decorations.
My question is, if I have no other corals, anemones or such, will this small (>1") anemone be a hazard to my much larger fish? Because, to tell the truth, I think its kinda cool that it just spawned naturally and I dont want to kill it if I don't have to.

No it shouldn't be a problem the reason they are a pest to reef tanks is because they will out compete the corals for light and they can clone and spawn pretty quickly. But in a fish only tank they might actually be considered benificial as they would help consume some of the nutrients in the water.

Mine stung/wiped out a whole colony of fantasticly-colored zoanthids (called pumpkins) & really cool-colored clove polyps (orange & green).
