Emerald crab, Mithraculus sculptus
Introduced on the 31st May 2018. Found to have a taste for SPS (mainly Seriatopora hystrix so caught and move to the refugium on the 3rd June 2018. Sadly Bruce died on the 8th December, I think Charlize killed and eaten him! I'm so sorry Bruce, RIP.
In the refugium and living the life of Riley, happily tucking into the grape algae, that must taste better than SPS surely! 10th June 2018.
