So I have a 50/50 shot or better,,same odds I had when I bought my picasso and he is a real sweet heart.I found the key with him is to keep him feed.
I am thinking about getting a puffer,that is one of the fish I have ALWAYS wonted.The LFS I deal with will have a porcupine puffer waiting for me if I wont him next week.
My CC star and urchin are about the same size and have never bothered each other.
