Maxima clam moving itself

[Jan]

My 5" teardrop maxima is either jumping or falling off of its rock onto the sandbed. I'm wondering if I should leave it on the sandbed, like maybe it wants to be farther away from the light?

Recent changes:

~10 days ago I upgraded the lights on its 30 gallon tank from a 150 to a 250 watt halide, which it seemed fine with (no jumping), but a couple of days ago I started to run a half liter of zeo rocks in a "reactor" (at 60 gph). I used a slow startup process with pump running 3 hrs on and 3 hrs off but after 24 hours I noticed some photo burn on some of my sps. This would be from the water being cleared by the zeo-rocks. I'm wondering if the clearer water/more penetrating light might have caused the maxima to want to jump? In it's previous spot on the rock it was ~16" away from the bulb.

Is it harmful for it to be on the sandbed? I may have bristleworms in that tank--I used to, anyway, but I moved a few rocks out so maybe they left.

Jan, I have my clams in sand bed (6) and two of them move all the time. One more than the other. I will follow along. You may be on to something .

its not jumping, it doesnt have leg's

how did you acclimate it to the new lights?

if your light is strong enough to reach the clam on the bottom it should be fine there. dont worry about your average everyday bristle worms they are totally harmless

I didn't do anything to acclimate the clam to the higher wattage and it didn't seem to have any problems with it...it didn't "propel" itself off the rock face after the lighting change, it did it 10 days later.

im just trying to joke a little

lighting changes can have dramatic effects on clams. clam try to regulate the amount of food and O2 there zoox produce for them by allowing them to increase there population or by expelling them. if they get a drastic increase in light it can be hard for them to dump the extra zoox fast enough, causing an increase in O2 internally(along with glucose that also needs to be dumped) this can definitely upset a clam and cause it to have a reaction like you had. for the clam to feel the effects of this it will take a few days, not over night.

OK...that's very interesting. I hope it is okay and not hurting by anything I did.

thanks for the info.

my clam also did the same thing...

it did not want to be on the rock.. it wanted to be in the sand...

it does move it self around with its foot from time to time... no legs just a foot
