Euphyllia sweeper tentacles.

[tyler1503]

Being a huge euphyllia fan I'm always looking at them at the LFS. Yesterday 2 particularly nice ones caught my eye and I'm considering getting one. A "peppermint" euphyllia parancora and also a "peppermint" euphyllia ancora.
But then I started to think about the sweeper tentacles and what available space I have. The reason I've never put one in my tank is I only have a 5gal set up for corals and too many corals I don't wana risk getting stung.
With all that out of the way, I would like to ask, how long do most hammer sweeper tentacles get? Would I be able to house one in a 5 gal without it killing everything else? I seem to remember reading 2-3 inches somewhere but feel the need to check with r2r.
Thanks everyone!

I have a few hammers, forgspawn torch coral. Never saw them sting anything. People say im lucky.
Anyway, i would say 3 diameter from what they are when closed. My torch will extend itself a bit more, I consider that one the most likely to be sweeping since its 1 or 2 tentacles that get really long in comparison to its half inch skeleton. I've posted a few pics of it literally feeling up my hammers and never an issue.
That same torch is pretty close to my bubble nem now and no issues either.

Both hammers mentioned the wall and the branching have tentacles that will sting. Technically euphyllia do not have sweeper tentacles. They can extend the constant visible tentacles length several inches longer than the normal extended length. Sweeper tentacles are separate defensive tentacles that have a stronger stinger punch. I never saw one called peppermint guessing it is reference to the color. I have see ones called mint as the color was a flat mint color.

5 gallons is small. The para hammer aka branching is far hardier than the wall. All non-para forms are less hardy than para forms. The walls do have longer tentacle reach than para forms. Para forms will grow more vertical as the non-para wall forms are restricted to horizontal growth.

Yea, peppermint is a colour reference. I assume they are the same as the mint ones your talking about. They're a pale minty green under normal lights, but glow like crazy under actinics.
Everything else in my 5 gal has been very docile for quite a while and I don't have any issues with aggression. I don't wana mess things up by adding euphyllia if they're likely will kill everything. Thanks for the growth pattern info and I didn't know branching euphyllia were hardier than the others, I see the branching species very very rarely around my way.

Euphyllia can touch each other without issues, but other corals can be stung. My concern is mainly my cynarina and candy cane colony.
Do you mean a 3 inch diameter, or 3 times the size of the head diameter? Lol. I seem to remember reading 3 inches once.

for example my torch and 1 of my hammers, i just posted pics of in the LPS section a few days ago, the head is about .5" but opened the hammer is about 3 inches. the torch extends about 2.5- 3 inches but there are like 2 tentacles that reach about 5 inches away from the base of the head and it literally rest on the hammer all the time.

i seen a video once where a nem was moving in on a frogspawn and everytime the tentacles of the nem would touch the frogspawn it would retract and they seemed to be at a standoff, while the nem kept looking like it was getting stung and hurt, the frogspawn seemed largely unaffected, which clued me in to just how strong these guys can be

lets see if this will work *not my video btw*

Thats interesting....
I always wondered how that would work...

I saw someone on IG post one time how their elegance would sting the crap out of her nem if the nem intruded...
I feel a little confident knowing that. Maybe that will keep the nem in place if mine ever tried to move...
Although my nem seems very happy.

Maybe i can trap the nem in that corner by sectioning off with more elegance... lol...

I have a rock w/rainbow BTA that keep dividing. When i turn off the pumps to feed the BTA tentacles go limp. They droop and if they touch the frogspawn below they quickly snap back as if the BTA was just shocked. Euphyllia have enough power to do damage if they want. I find torch to have strongest sting while hammer and grape corals to be less. But this does not mean they can not defend their territory if needed. My branching hammer can elongate tentacles 2-3" from skeleton base. Torches are also notorious for suddenly even attacking other euphyllia species.

This is an old thread, but does anyone know how far a torch's tent ovals can reach? I have a torch about six inches below my Palmer's blue milli and now my Palmer's has a dead spot, Is it the torch?

Depending on the size of torch 6" is nothing to reach to. The ability to sting the acro is totally dependent on if the flow is in the torch's favor. If it is a sting from the torch it should heal. As long as it is not stressed from other things.
