You leave your clams exposed to the air??? At over $100 each and getting harder to find nowadays, that's not a risk I'm willing to take.
Also, sponges exposed to air can very quickly die and then you'll end up with dying sponges creating an ammonia spike & you go through a mini-cycle. Ornamental sponges are hard enough to keep alive as it is without the added stress of air exposure.
For these two reef inhabitants, a few seconds is not a big deal. However, if they're going to be exposed to air for longer (which is usually the case when completely draining your tank, catching the fish and then refilling the tank), I would move them to a holding container to stay submerged during the whole process.
