Tank is very rich in all kinds of life mixed together. Lots of nutrients and no more sock filtration or water scrubbers. It is a fairly mature scallop, about 3"+ from front to back. It is in the sand. Moved himself around until it found a place it liked and glued itself in place. I feed the tank different flakes, Mysis, frozen blender-ed stir fry mix (clams, scallops, squid, shrimp, etc), and an occasional squirt or two of Liquify Marine (some old style egg protein, etc based stuff). I also put a bit of powdered foods in occasionally. such as Reef roids, OSI micro, . These are different brands. Mostly stuff accumulated through the years. My general philosophy is the better the variety, the better the nutrition. Corals are growing, fish are healthy and happy, inverts thriving, shrooms, zoas, and rics propagating, and the scallop has grown 10-20% in the last year I had it. HAVE NEVER ONCE SPOT FED IT. It finds all it needs and wants in the water from detritus and misc particulate foods. Hand feeding phyto to the young maxima clams and started adding some Kent Zooplex. I got a 32 oz container included with some live rock.
After reading that excellent artical, seems that the scallop found a good place and is happy filtering out small enough foods out of the water to thrive. I have some pretty major water flow for the typical sandy bottomed tank and the sand is constantly being dug up and moved around by a sand star, conchs, misc other snails and hermits, a lawnmower blenny, and the changing currents. Running two SEIO 2600s with a controller plus the pan-? pump return and once or twice a day, turn on my Iwaki 40rlxt hooked up to a spray bar. Fuge full of mixed caulurpa and chyto. Never a day that some particulates are not being stirred up for at least an hour. I can not imagine a scallop surviving a sediment free tank.
