crocea not responding to shadowing

[Ritchie]

i have a crocea that was fine for a couple of days i got him on tuesday, he was fine up until last night when the lights went off it stayed open, i think its still alive because it will move its mantle and it moves its mouth, any ideas of whats wrong with it

Mines usually always open. They're filter feeders so they're constantly eating. Photosynthesis doesn't provide enough food for them

Pretty much the same as SPS, but some clams prefer dirtier water, since their primary nutrition comes from filter feeding.

I'm new to the whole saltwater thing please explain

If you have a refugium phytoplankton and zooplankton can multiply and that's the main food source of these clams along with photosynthesis.

Would mysis shrimp be a good supplement

Here are a few links to care articles for a few of the most common aquarium clam species.

thanx drew alot of good info on the links...any advise on if they should be keept on rocks or in the bottom on the sand?

 

[Drew Shark]

Some people put them on the sand if they have powerful enough lighting. People will also place them on the sand if they are afraid of them unlatching and falling on other organisms in the tank. However you can place them on the rocks if your lighting is less powerful or if it looks good to you and the clam seems happy.

I've heard that crocea, being rock boring clams by nature, should be placed on rock, and can actually be irritated or injured if placed on the sand bed. I can't say for sure, but that's what I heard.
My crocea is sitting in a depression in my rock work, about 3 inches from the water's surface, about 8-9 inches from my 150w MH, getting blasted with flow, and it's loving life.
