top of the new clam

that clam has awesome color! What is gaping and why is it a problem?

its gaping because its new to the tank. gaping means the clam is under stress

that clam is magnificent!

how can you tell if a clam is "gaping"?

um...its open more than it should be, lol...i actually just started a thread based on what 'gaping' was...i think when the valve is open alot. thanks guys
