Elephant Ear Mushroom = Fish Killer???
I purchased this Giant Mushroom from a fellow reefer. He was not sure exactly what this mushroom was and it was sold to him as a Giant Creeping Mushroom. I believe it is actually an Elephant Ear Mushroom of some type and have read that they have a potential to capture and kill fish. Anyone have any experiences with this variety? Should I be worried about my fish??
This mushroom is atleast 10 inches long with 5 mouths and a green blue color.

Yes you should be very concerned, You must pack up your Copperbanded Butterfly and send him to me immediately....
 Just kidding...There isnt a ton of info that I can find on these giant mushrooms, I cant imagine it eating a healthy fish..but if in doubt, send it back...

I have them in my RSM with tiny fish; Eviota gobies, Trimma gobies, Yellow Clown Goby etc...they perch on it, and it's just fine.

I've had one big Rhodactis mushroom that closed up & killed my Mandarin goby that was too stupid to move off it as it slowly closed over the fish. I saw the fish sit on it, then I went back to work. Next I saw that the mushroom was closed up & it slowly opened to reveal a dead, but uneaten fish.

Once they get big enough, yes they can and will eat fish. Mine ate about a quarter of a clown
 And it was smaller than yours. It kind of just released the rest of it. That was a few years back and I have never kept those mushrooms since.

I've seen pictures of mushrooms eating fish. I'm no marine biologist but I'm pretty sure mushrooms are in the same family as anemones. I wouldn't want a threat like that in a tank your size. I'm actually pretty sure my carpet anemone has caught a fish or two in my tank
You might want to sell it or trade at a LFS.

from what Ive seen mostly perching benthic fish like gobies and mandarins are still enough to get caught. Ive seen a clown get caught too. Yes they are related to anemones to a degree but these guys rely more on slowly closing and trapping a fish rather than stinging it to death as an anemone does. I too can't say I see it picking off a wrasse or CBB, but no guarantees.
sure is a nice piece. if you get rid of it, be sure it goes to a decent well-suited home.

My false percs hosted in it when it was in their tank...strange it's been in 3 different tanks with slow moving, small, fast and large fishes with no problems...weird. I really like mine and it's done well....

Ok, after taking a closer look at your shroom, it looks very similar to the ones I have in my tank & those I've never seen try to eat any fish. They are long and narrow, whereas the fish eater ones are round. That means, to me, that its sides are not very wide & it would be much more difficult to close up completely over a fish. Beautiful coral.
