If its not sufficient for an acro, theres no way itll keep a maxima alive for long. The young seed is later raised in up-wells, containers which allow algae rich water to be pushed up through the juvenile clams, thereby allowing them to feed continuously and grow rapidly. When open, the bright blue, green or brown mantle is exposed and obscures the edges of the shell which have prominent, distinctive furrows. Anatomy . Wells, S.M., Pyle, R.M. Put it this way: If its bright enough to grow acros, then it might be bright enough for a maxima clam. Small ones are really cheap on reefscience and I was just wondering how fast they grow? clams to grow for 6-12 months without being moved. Shell solid, equivalve; inequilateral, beaks in the front half of the shell; broadly oval in outline. The Bivalves have two valves on the mantle. Bright lighting such as that provided by metal halide aquarium lights or Strong LED Lighting or a combination of T5's plus other lighting is an absolute necessity, in that most clams generate energy by photosynthesis as well as by filter feeding.

Hermaphroditic clams release their sperm first followed later by their eggs, thereby avoiding self-fertilisation.[2]. i.e. The attractive colours of the small giant clam are the result of crystalline pigment cells. [2] The juvenile matures into a male clam after two or three years, becoming a hermaphrodite when larger (at around 15 centimetres in length).

(1983) The IUCN Invertebrate Red Data Book. After a fifteen year absence from the reef aquarium hobby Tridacna gigas returned through the farming efforts of Oceans Reefs & Aquariums better known as ORA. The hard clam can live up to 30 years and grow to (on average) 4 inches in length. Hard Clams . Reproduction is stimulated by the lunar cycle, the time of day, and the presence of other eggs and sperm in the water. The clam is considered a juvenile when it reaches a length of 20 cm (8 in). [2], Beginning life as a tiny fertilised egg, the small giant clam hatches within 12 hours, becoming a free-swimming larva. The giant clam, Tridacna maxima were reared in cages in the sea; measurements of the shell's length, height, width and buoyant weight were taken under water to compare the growth rates of different size groups of T. maxima.The results showed that the specific growth rates were significantly high in the smallest size group and decreased with increasing clam size (P < 0.01). Clams are best in well-established aquariums that have had several weeks or months to cycle. Some of them can double their size every year. They live in waters from the deep sea all the way down the street from me in our not so clean river in Indiana. New posts New posts (unread) Current visitors Latest activity. After eight to ten days, the larva metamorphoses into a juvenile clam, at which point it can acquire zooxanthellae and function symbiotically. On average this clam will only grow.08 to 1.6" per year, rather than the 4" per year seen with those two big fellows.
