Pectinia (spiny cup, alien cup)

Anyone have any experience growing Pectinia in their reef tank?

I have one and it appears to be a fairly hardy coral so far (I've had it since 2007).

When I acquired it from a $5 assorted coral frag tank I though it was a nickel-sized light-green mushroom coral at first when I selected it:


...except that it was evidently a stony coral when I handled it.

It developed into this: (these photos are a few years old it's a lot bigger now, with a lot of ridges but I do not have any recent photos of it as of yet):




Pectinia seems to fair well in moderate lighting. I've since moved it to a higher position in the tank and upgraded my lighting and it appears to doing well under greater lighting conditions as well.

It accepts food readily at night (mysis shrimp) when its tentacles are extended but does fine without feeding.

Speaking of its tentacles, pectinia can cast some fairly long sweeper tentacles nightly. In the last photo they extend clear past the right boundary of the photo:

Great pics! Yes, Pectinia is a LPS. Many websites have copied and pasted that it's an SPS, which we can clearly see from the pictures that this is not true. I've kept a couple of these here and there and find them to be a very interesting addition.

Yeah it's definitely an LPS. I'm just hoping its doing ok I've had it for months now and it seems fine. I have it under a 120w Blueline VHO Led(the lights about foot above my tank) and I had the pectinia at the top of my rock work for a while and then moved it more towards the middle and just yesterday i loved it to another middle area off to the side where there is some decent flow. I'll try to post some pics.

Pectenia

I also have a pectenia, just wondering why mine has never extended tenticals at night? I've had it almost 5 years. I added a tru lumen deepwater blue led light and it started bleaching a little. Moved it to a shady spot hopefully it will get its color back

Yeah man mine recently start receding and bleaching at the tips. I have completely covered now hoping it recovers. But i have also never seen tentacles at night....it extends tiny feeding tentacles that are very tiny.

Pectenia cup

I've never seen any tenticals, but the mouths of each piece do open up during the day. Idk if bleaching is the correct term for mine it just looks a little more pale than usual. Almost as if there is a white haze over the coral. It's deeper greens have lightened up

Here is a pic with good color
