6 line wrasse and short spined sea urchin
 

Hi, everyone.

I am taking over a 75 gallon saltwater reef tank for my son while he is away in college. I have been working with him on this tank for the past 5 years. He has just put in several weeks ago our only fish---easier without them. And, I am concerned because I have read the 6 line wrasse may eat sea urchins. We have had a short spine sea urchin for the past 5 years. I am wondering if the urchin will be fine or not. That is the question.

I appreciate any assistance.

Nope, the urchin should be fine. A six-line wrasse is a very good choice. They tend to be hardy and will rid your tank of pest worms. They make excellent reef fish.
