I have an urchin that came in as a hitchhiker which might be a pin cushion urchin. She's been increasingly active lately and I'm concerned she might not be getting enough food. I offered her some Nori but she doesn't want it. I found an estimate that they can reach eight inches but the same site listed a twenty gallon tank as adequate.
Should I be worried about her food supply? What is a good sized tank for a pin cushion urchin? My tank is around 55 gallons in display (250 liters) and she's around 3-4 inches right now.
Thanks!
