With the lights you have it may be possible for either
T. Squamosa or
T. Durasa. As indicated above, you will need to feed with phytoplankton (preferabley live cells) if the clam is on the smaller side but if so, be sure you stop using the
UV. It will hamper your success. As the clam gets larger it will become more light dependant and target feeding less necessary.
