I currently got a 150watt MH with a fluro actinct light. I already got an electric blue clam in my tank (T. derasa) about 12cm. Im getting a 4cm Blue squamosa and a 8cm Gold squamosa off work tomorrow and they are under two 10,000K fluros with an actinct light. They are 40cm below the lights and i was wondering how would i correctly accumlate them? Treat it like a fish? But would i have to treat them like SPS? Like place them on the gravel first then slowly place them on the rock at a higher level in the tank?
