I purchased a small maxima clam hes been in a reef tank for months now and doing good. I have a 12g setup that's been going for 3 weeks and has cycled. Running a zetlight nano on it that will support sps and all so I know It can support a clam. With this guy being so small and the tank not that old (I used live rock and water from my main tank for setup) would he be ok?? calcium is up over 460.
