[I ordered from Marine center and got some rock 15lbs. with no life visible little corraline that wasn't good or bad for the money. They did sell me a large star polyps rock it was covered in coraline and had little bumps on it but only about 2 polyps will come out the rest look like little bumps were they had previsly been on there but covered in coriline, they said they should come out in 2 to 3 weeks. Is this true? They also sent me what they called flower coral but it looks like a mushroom leather coral. I don't know what the deal is but I exepect a call back today to see if they will resolve any of the problems. The regal tang was wonderful looking but the medium looked small at about 3-4" . I'll let you know what happens. ??? ???]
