When I first got my clam it was on the very bottom of the tank (24" deep) under T5’s, and it was WIDE open and sticking it’s mantle out, looking extra puffy and not as colorful. I raised it up higher and closer to the surface, a korlia 750 and a korlia 1050 power heads placed very high in the tank on opposite sides, pointing to their opposite corners but is not blowing directly on the clam (the power heads are pointed straight, just under the surface). The output from the sump is pointed way over the clam. The color has come back full force since I moved it, and it seems to be doing fine, but it’s mantle won’t come out as far. What’s up with that? Below is a pic to give you a better idea of placement.
just me, but i think there’s still too much flow. the left nozzle looks like it’s pointing right at the clam.
very difficult to say, but lotsa other possibiities.
what was lighting it in the place you got the clam?
how long have you had it?
is it attached?
water params?
bulb age?
a list of inhabitants might also provide a clue or 2.
logically, if it was as open on the bottom as u say, maybe it wasn’t getting enough light, and now it got shocked by a quick light intensity change. the thing above it is whited out
We got the clam at PEA, it was in their greenhouse.
We purchased it on October 19th 2011.
It was bought attached to a very small rock (a small fingertip’s worth of foot was still unattached, but it looks as though it’s attached to the current rock and not going anywhere).
Water params: 0-0-5 (five nitrate), calcium is 450, salinity is 1.025, pH 8.2 to 8.3, and we don’t have a reliable phosphate test, however all water is RO/DI.
We’ve had these bulbs for two months now.
Inhabitants: Numerous hermit crabs (red leg & blue leg) and snails (turbo, mexican turbo, and margarita), a single tiny “flame crab” who just burrows and hides in the sand 24/7, a tuxedo urchin, a green serpent star, a tank-bred fancy ocillaris, a small naso tang, a psychedelic mandarin, and a single green chromis. Also tons of corals (zoas, acan lords, carnations, pulsing xenia, star polyp, hairy mushroom, frogspawn, brain coral, candycanes).
Here is a photo, better angle to see that the nozzle is not pointed at the clam (the one seen “on top” is the left nozzle).
We were told that the a) decrease in color was a bad thing, b) T5’s weren’t strong enough to penetrate 24" of water, and c) we were afraid it would get sand into it’s mantle, though we have since gotten rid of our sand-sifting goby, which was the main cause of our sand-in-clam fear. But no, we haven’t tried moving it back, to answer your question. We turned off one of the power heads to see what that did, if that fails we could try moving back.

bill, why would it close, though?? not that i’m concerned about moving it back. they don’t mind as much as many corals.
pea maxi again. hmmm. i lost another of mine from there. been in the tank since summer, 3-4 months. i’m stopping getting them, as my little ones do better. the crocea from him is doing very well. maxis just seem to be less hardy. numerous losses, by me and others!
stone, [sorry i don’t know yr nam]some pea clams don’t open wide, if i remember what dr mac said at the mtg.
Jess and Josh, two people, basically one in the same. Ahoy, matey!!
The clam is definitely feeding, and it’s reacting to shadows and such, and looks different through out the day. And it does open, but the colored mantle just won’t stick out as much, like it’s not getting puffy, or swelling all the way with water.
Ugh, we do not want to lose a clam.
ahoy back. how do you know, observationally, that he’s def’ly feeding?
do not feed your clams. james fatherree [get his book, giant clms in …] says that, more than once.
Well, its siphon hole is opened most of the time, and it’s not gaping too wide, and I know not to spot feed him. I spot feed the carnations, acan lords and the brain and blastomussa, but not the clam. I figured that if I’m spot feeding around it, it should be fine on its own.
