New Clam Still Problems

[dcombs44]

I bought a crocea about a week ago. He attached quickly and was totally opened up the first night. Since then, he keeps falling off the rock and is open but the mantle is not pushed out over the edges of the shell. He will push out to the edge of the shell, but never spills out over the edges.

PH 8.3
Temp 80 F
Ammonia 0
Nitrate 0
Nitrite 0
Calcium up around 500
Alkalinity just a bit low
Lighting 175 watt 14000k metal halide
2 20 watt 03 actinics
29 gallon tank

Here is a pic from the top and side of what it looks like most of the time

 

[dcombs44]

Yeah kinda....it almost looks tattered

 

[mbbuna]

that clam is very weak. is the shrimp still crawing all over it?

 

[mbbuna]

as weak as that clam is i dont think there is much that can be done

 

[dcombs44]

no the shrimp is leaving it alone

what would make it so weak

 

[mbbuna]

it could have been weak when you got it. if it was kept under less then ideal lighting/water at the lfs,supplier,wholesale,or disease. its hard to say. clams can be dieing and look good untill one day,gone.

 

[dcombs44]

yeah....it did look good when bought...under 400 watt mh at the store and good water....same that i use....maybe there is something missing from my reef supplement?

What is a must for clams?

 

[mbbuna]

Ca/Alk ,light ,clean water ,not being pestered

 

[dcombs44]

my lfs is good to take things back and try to bring em back to "life" so to speak....maybe something in my system is causing it problems....i had such a rough start with my tank that there may be something in there that we cant see or detect. maybe i'll take him back and see how he fares

 

[dcombs44]

last question......do you target feed your inverts and corals......my lfs says no need that the plankton/cyclopeeze spreads throughout the water column good enough...

 

[dcombs44]

could too much water flow be a problem for it

 

[mbbuna]

i dont intentionally feed my clams,just light. as for flow unless its mantle was flopping in the breeze, i doubt it
