Hi! I’m new here and also new to aquarium management. I am a little concerned about our pincushion urchin. We have had him about a month. He’s very active and moves all over the tank constantly. He looks healthy and doesn’t seem to be losing spines. But here’s why I’m concerned: the first few weeks we had him he was collecting things and carrying them around 24/7: snails, little crabs, rocks and shells and debris from the sand. But in the past week or so he hasn’t collected anything. I’ve read as much as I can about these guys and can’t find anything about why they might STOP collecting things. As for the tank, the water and levels are perfect (just had them tested). Is it ok for him not to pick things up anymore?
I’ll attach some pics. These are all of him now, and I think he looks healthy and active other than not collecting his little treasures.
