I just bought two new max clams a couple of days ago. I followed all the tips with acclimatization. My water parameters are good. I have 2 - 250w MH and 2 96wpc actinics. My clams are about 2-3" and they are on a rock about 22" directly under the bulb. My concern is that the mantle are not fully extended. They barely reach to the edge of the shell. My temp is a bit high due to the summer heat. It is about 84. Do I need to do anything to ensure the survival of the clams? Should I wait until they settle into their new home?
