what is wrong with P's clam?

I did burp it. yes.

 

that did not occur to me. i'll keep an eye on it with this in mind.

it came from under MH (I'll post their specs when i can pull 'em up) about 12" under water with the MH a good 12" above the water.

I have it probably around 8" down under those T5's mentioned earlier. my lights are about 4" from the water.

 

maybe its not getting enough light. croceas need a lot of light.

 

That is what I am thinking.

So you have 2 UVL SA's and 2 UVL actinic whites?

Neither of those 2 bulbs are very good at making PAR.

I would instead run 1 ATI or Geisseman aquablues, 2 ATI blue+, and maybe 1 of those SA's by UVL.

Lighting is such a personal thing, but I can say you should run at least 1 aquablue in there, and for blue bulbs, the ATI blue+ can't be beat for color or PAR.

It appears to me the UVL lights are just not cutting it for light for your clam. All the PAR tests I have seen rank the UVL's pretty low in PAR compared to ATI and Geisseman.

 

+1 to what horkn said

 

Any updates P?

 

I've increased photo period.

The spots aren't so much spots as they are a general lightening of the mantle now :-/

It still extends its mantle, reacts to stimuli, etc... So I'm thinking it might be just getting used to the light. I have about another hours worth of increase to do on my photo period over the next week...

 

Glad to hear it's hanging in there!

 

I noticed in the first pic the clam looked like it was wedged in place with a shell of sorts but in the 3rd pic it looks like you epoxied it in. Clams are kinda funny. You might think you have it in the perfect spot but they always seem to jump around on their own to find that just right spot. Maybe its not happy being glued down?

 

no no, i have not epoxied or glued this down in any way. It's not even wedged, it's sitting on a little shelf outcropping of the rock that's behind the rock infront of it. So I guess it just gives the impression it is wedged and/or epoxied.

It is completely free to move - but it hasn't moved at all.

The rock in front of it is epoxied... maybe that's what you are seeing...

I agree with your point though. I don't think I would ever glue down a clam.
