I have a crocus clam in my tank which came attached to a smal piece of live rock. He’s been happily there for a good few months but I’ve noticed that my sand dollar has decided this is his area now and is constantly churning the sand. The clam has now detached himself from the live rock and is sitting horizontal (where previously he was at an angle) is this normal behaviour?

Not sure. Sand dollars are not compatible with home aquariums though, as they need a huge amount of sand fauna to eat.

Cheers I didn’t realise that the sand dollar would be a problem. I bought him with a few of the other inhabitants of the tank from reefer selling up., so might need to look at moving him on.

I'd look into donating it to a decent public aquarium.  It's unlikely to survive in a home aquarium from what I've read:

Hi got really worried about the sand dollar but apparently they can live and thrive in reef aquariums. They feed on most suspended organic (fish waste, algea, and detritus). Although you tank does need to be very mature for them to survive.

Interesting yes, but also destructive. Only ever see him at night around the front of the tank. I moved the clam away from the sand dollar’s normal  path but he’s changed his route to where I put the clam  >:(

Can you lift the clam off the sand bed?
