Very very odd. Like I said, our largest yields are in the middle of the summer. I find this to be true in the natural habitat as well, something I have been visiting all my life They do not live in the ocean, they live in the upper splash zone, which is different then your normal tide pools. The upper splash zone gets pretty darn hot in the summer, 90's in the day and cooling off to the mid 60's to low 50's in the night. They rarely get hit by the ocean, maybe two to three times a week (accept in the winter). We just put up our heaters for winter to keep our numbers up.
