New Crocea clam help

[TimT]

Clams don't like it when the current moves the mantle. If the current is rocking the clam then find a different spot or change flow pattern.

Several reasons I avoided putting clams on sand; worms attacking the clam from underneath, they blow the sand around when they suddenly close and they will attach to the bottom of the tank unless you have a 3"+ deep sandbed.

It's best to give the clam something small to attach to. A small rock up to 4" or shells are fine. This is so that if you need to manually remove parasitic snails the clam can be easily removed from the tank. Clams can firmly attach in 16hrs if they are healthy and happy. New clams will jerk their shells closed if a fish passes near, this can cause them to tip over etc. Cleaner shrimp may irritate clams.

Crocea's like the most amount of light. I have seen them under full sun in 6" of water. I would put it in a brightly lit spot within a day.

If your clam is smaller than 2" I would feed it some phytoplankton.

Hope that helps.
