Emerald or Gorilla?

[HarryC]

Got this coral killer last week. ID? Doesn’t look very emerald, more white to me. He/she very much enjoys the taste of euphyllia flesh.

They can be pale almost white or pink

Yup, emerald. To the upside down with him.

Emeralds generally pale out when they don’t get enough algae to eat. I keep three of them in my 40 gallon and weekly hunt them out and give each of them an algae wafer to munch on. Helps keep them from going after coral.
