I have a contact in Ontario who supplied me. He did a bang up job shipping them to me. Not sure he ships regularly but did me a solid. He has been breeding them. I received about a dozen for my 150 gallon mixed reef. They seem to disappear once I put them in my display but I do see them the odd time at night cruising the tank. They completely eradicated all apps from my sump in about a week and beleive me I was overrun.
Here is his email address if you want to shoot him a message. His name is Chris. Be aware that they are not cheap.
