Picked this up and the guy didn't know the name of it... neither do I. An ID would be greatly appreciated. Thabks

From a picture looks kind of like horn coral hydnophora

 

[duke62]

Yep

 

[fredro]

Thanks buddy! It sure looks like it from the pictures I saw when I googled them, but the only difference is that this one doesn't seem to have any polyps extended. I know that it may not be opened because I just put it in the tank, but if looked the same way when I picked it out. Are there different types that have more or less polyp extension, or is this thing just unhappy and closed up?

Def a hydno. Polyp extension will vary with how happy it is. Better extension usually means it likes it's environment. Just give it time.

It's also know as the coral killer

It's also know as the coral killer

Please... Elaborate.

 

[Jazeel55]

It's super aggressive If it touches other corals it will kill them

Where did you get it from ???

 

[fredro]

A friend out east, I traded him a 4 headed red acro frag for it.

mine does better under low light thats when it extends its polips the most i have a smaller one up higher in the light colum and its polips are not extended nearly as much its a pretty fast grower

 

[fredro]

I have it on the sandbed now and it seems to have expanded quite a bit, doesn't seem to have actual normal SPS polyps, more like its inflated like a LPS.

 

[Jazeel55]

My piece

 

[fredro]

Here it is "opened up."

 

[Jazeel55]

Mine has never puffed up just polyp extensions

For years people have argued whether or not it was LPS or SPS. With it's stinging sweeper tentacles I would treat it like an LPS coral. The only coral that is more aggressive is Galaxea
