View Full Version : plate again
I have a new short tentacle plate. It comes out moderately at night, poofs a bit, has a lot of feeder tentacles in rings around the mouth. It excretes. It has tiny feeders out by day. I've seen plates look a bit more---ahem!---luxuriant. Can I expect more expansion? It is near but not within striking distance of a pearl bubble: I take it they move if they don't like the neighborhood. It is in high light, under a 250 mh, at a distance of 20 inches, under good flow.
Well, I moved it a little further from the pearl bubble, and into a slightly calmer area. It looks a little pleased, ie, the tentacles are a hair fatter, but no expansion of the base. Sigh.
And a week later, it's now eating voraciously (shrimp bits) but still stays retracted.

So do, some don't. Most plates remain retracted during the day in nature. I don't think that there is any rhyme or reason to which one expand during the day and which ones don't

what is your salinity and how is it measured?
In other words - do you trust what you measured it with.
Many LPS will not "get really plump" if the SG is low.
Mmm, I'm 1.024 with a well-calibrated refractometer.
That's interesting---I've been attributing an ever so slight recalcitrance of a pearl bubble to over-feeding (it snagged 2 pieces of shrimp). It could be because the salt got a little lower during water change, due to a jostled topoff float, maybe down to 1.0235.
I've raised salinity a fraction; I've fed it extravagantly, and finally added some Kent coral micronutrients. It is now fluffing out a little: tentacles are a fraction longer and the rim is rippling a bit. Meanwhile the adjacent pearl bubble has gone ecstatic.
