    I recently bought a urchin that dies one day after I put it in the tank, it dropped all its spines and died. Also about 3 months ago I bought an urchin that did the same thing. I can't figure out why they are dying. Does anyone have a clue of why they might be dying.

    Lack of food, water quality, what are your water readings especially nitrates

    I wouldn't think it would starve I have plenty of hair algea in the tank and before I added it to the tank it tested close to no nitrated

    Urchins need to be drip acclimated very slowly

    30min for drip acclimation and 20 minute of floating it.

    Typically I drip urchins for a couple hours.

    The guy at the saltwater fish store said that because of the cold I should only drop acclimate for 30min or else the water will start to get cold.

    I'd put a small heater in the container you are drip acclimating in. Urchins are very sensitive to changes. This goes for all urchins.
    If the volume is too small for a heater you can place a small container inside a larger container of water with a smal heater. This will keep your temp good and increase the chance your urchin will survive.
