Tank is very young, but the sand and rock came from an existing tank that had been up for about 9 months. Water is stable, and it seems like lots of food on the bottom. This guy just hangs there near the protien skimmer, and extends all these pink christmas tree like feathers to filter feed from one end about three times a day. I am giving them bio plankton, and he seems to feed just after I put it in, but he is still shrinking. He doesn't seem to care about other larger food items floating around. Is there anything else I can put near him or among the filter feathers that will help? Should I risk pulling him off the glass and putting him back down on the sand bed? Beyond filtering water or sand what do the spiney little twurps eat? Any ideas?
