black spine urchin and flame scallops OK?

[mdvistnes]

I was thinking of putting a black spine urchin in my 180 reef tank. Does anyone know of any incompatibilities with them? Anyone regret putting one in their tank? No downside?

And I had a flame scallop once that didn't last too long but was thinking of trying again. Any advice on scallops? Thanks in advance.

Please don't! They have a very poor liife expectancy in captivity.
