    Hi my sea urchin is just sitting at the bottom corner of my tank. With closer inspection I noticed small jelly like bubbles in the area between the urchin and d glass.
    Can anyone tell me what's its up to. Could it be eggs?

    Can you post a pic of it?

    Sea urchins are broadcast spawners and release eggs/sperm into the water column. The eggs are tiny and round and wont really settle on anything. They also released from the upper hole, the one on the bottom is its mouth.
