bubble coral help…

[samrggzy]

So I have had a bubble coral in my 32 gallon biocube for a few months now and I need some opinions. I have noticed that almost all of the time the coral does not look fully “inflated” and extended as it should be. It always has its feeding tentacles extended and the “bubbles” are not very large. I will add pictures to show what I mean but im just curious to why it looks like this most of the time. All other bubble corals I see at stores have large puffy polyps and mine never seems to have those. It is not closed up, just doesn’t look like it should. My current parameters are listed below:

temp: 77.7
salinity: 1.023
alkalinity: 8.0
calcium: 445
nitrate: 3
phosphate: 0.00
ph: 8.0

There are a couple different Bubble coral varieties out there. The one that you most commonly see is the one like the picture we've attached below. It is a different type than the one you have. Your appears to be very healthy. I would not be concerned about it.

Nothings going to be happy with 0 phosphates, if that posted number is correct.
Bump that up and maintain constant level, whatever your maintenance regime dictates.

I would feed it fish food daily to counter the 0.00 phosphates. Other than that, it seems fine to me.
