Clam Queston

ok i know this is a very common queston and i know there are alot of negative answers but i just want to get another thread out there to answer my questions.

I have the standard AP 24g with the pc lighting. I have a perfect spot for a med. sized corcea clam that is about 2-3" from the surface of the water. IMy feelings are that with it that close to the lights that the intensity...even from pc...would be enough to keep it healthy and alive?

Has anybody had luck with this or has anybody tried it at all?

Just looking for imput!

Thanks
Randall
 
In the 140 (before the flood) I had a T. crocea about 10" below the surface and a T. deresa on the sand (~ 24") with 7x96w PCs. Both did well and grew for about a year.

Then I converted to T-5s and both seemed to do even better--the deresa especially seemed to thrive under the brighter lights and added half an inch of shell width in six months.

So, I guess a lot would depend upon how many watts of PC lighting you have.
 
well i have 2x32 pc's over a 24g. But with the amount of displacement i have there is only about 18g of actual water in the tank. I know watts per gallon is a good calculation but its at about 3.5wpg.
 
I have a 46 gallon and have 2X96 watt pc lighting. Ive had my clam for almost a year now and it seems to be doing fine. Its about 10-12 inches from the lighting.
 
can you do it. yes. should you do it.NO

can you live for a few years on a reduced diet? yes will you live? yes. will you thirve and have all the energy you need?no.
I think this shows my position on keeping light intense organisms in less than ideal situations.
 
i agree croceas are the most light hungry of all clams. pc's will do but not fot long. halides are really the only really good source of light for them.
 
Im not sure if the clam that I have is a croceas or not, but it is doing a lot better than it was in the fish store. It looked like it was on its death bed. I got it for 10 bucks and it seems to be fine now.
 
if you can take a picture of the side of the shell i'll tell you what it is. i have had clams a long time and have gotten pretty good at there identification.

also for a comparision click on the little red house. i have a blue squammie, a dersa, golden tear drop maxima, a gigas and a 2 croceas. also a blue rimmed squammie in a nano as well.
 
Heres the only pic I have of it. If you cant id it by this pic I can take a side shot later.

it looks pretty bwowned out it should be o.k. under pc's it might have came in as a trade from someones tank that had a lower light level, because croceas are usually much brighter if they have been under a lot of light.
 
onegreenray--

I clicked on your little red house but couldn't find any clam pics. Can you give me a better link? Thanks!
 
Aren't the smaller clams ,the ones under 2-3", more of a filter feeder than photosynthetic? So couldn't you keep smaller clams under less than ideal lighting conditions for a while? The biggest problem i'd see is the slip-and-slide parameters prone to small tanks.

keep in mind as clams grow the calcium and light requirements increase. the coloring in the mantle is the photosynthetic algae that in turn feeds the clam. by browning out it is loosing its food source. low light equals less algae to produce the nutrients the clam needs. it will eventually die. youll notice the mantle not expanding as far then less and less untill it exhibits "gaping" then death.
if you truly are committed to the health of these animals you need to get it under more intense lighting. It also wouldnt hurt for you to pick up daniel knopps' book great clams.
fwiw
 
i will take some pics for you of my clams when i get back to ny. i am on vaction in colorado right now.

that clam is pretty browned out. also its mantle looks like it is really strecjing for the light. just like any soft coral if there isn't enough light it loses its color and will reach for the light or over extend it self.

i have a buddy who has taken some frags of zoos from my tank and they are twice the size and not as colorful in his tank due to he has less light in his tank. but remeber to much light and you can burn the corals out.

what kind of lighting do you have over the tank? also how close to the lights is the crocea?
