9 months MIA

[stkitts]

I introduced 2 horseshoe crabs in my 180 about 9 months ago. Last night I saw one for the first time. He made 1" channels all through my sand bed. I haven't seen these deep tracks or them since I put them in. What or where could they have been. It is doubled in size.

these crabs prefer to bury themselves,more than likley around the rocks
