The spawning happened on Oct 1st. I just checked the autumnal equinox and it occurred on Sept. 23rd so I'm not sure if there is a connection.
I've had the clam for about 3 years now and got it as a 2 inch little baby. My clam is all grows up now. I'm gonna have to have the awkward bees and birds talk with it later this week. Its important that the clam know where baby clams come from.
