should I move him?

Since I've been getting into reef in my 54g should I move my long spine urchin? I have a 75 set up but not alot of coraline in it, that seems to be what he eats. The 75 has a lionfish in it and we plan to make it a predator tank. I think he'd be OK. Or not?

Despite my wife’s wishes I had to move our long spine to the refugium to keep it from eating all our coral. Don't be too quick to wish for coralline algae because once it gets a foot hold you will be scraping glass weekly to keep it at bay.
