Cup coral or cornyactis?

Any guesses? Looks kind of cool and want to keep it

pseudocorynactis

Keep or get rid of?

Ooh that's a tough call. Appears to be more like corynactis. If you get it to retract and it has a skeletal structure I would rule it as a cup coral

I have about 7 of the on the rocks in my frag tank for the past 2 years Nd havnt grown or done anything beside keeping my baby stomenella population down

So I have a phosphate issue, could this be causing it by overkilling snails?

 

[Sabellafella]

Personally indont think so, snails dieng wouldnt cause a long term phosphate issue, the way i look at it for elevated phosphate is from foods, not fully cured live rock(depending as it can take years for rock to mature) and not using rodi. If you find a graveyard of snail shells by the corynactis mushroom then yes it could be the reason, but depending on your tank size and maitnence

I loved mine. At first they blossomed, but over time they petered out. I enjoyed them while I had them.

I believe they're NPS so I would recommend target feeding if you want to keep it around

Shouldn't cause any harm as the tentacles are extremely short and they don't tend to walk around like other nems.

I have a cup coral that I found at my LFS on the base of a dying gorg. I offered them $1, took it home and have been feeding it every time I feed my dendros. It looks incredibly beautiful with long flowing arms with white nematocysts. It's plumping up quickly and almost looks like a baby rhyzo

If I came across a corynactis I would definitely keep it. I'm in to odd little rarities... Haha

I guess it will stay and I'll keep and eye on it. Thank you everyone
