What is wrong with this acro frag?

[Areseebee]

Apparently I'm losing this frag and I'm just curious if anyone recognizes what is happening here? Is this a symptom of something obvious?

Looks like the acro was recently being fraged, didn't even encrusted yet, Have seeing that way to many times on acros that was shipped to me.

Personally I will never going to by any more frags if they are not encrusted onto a frag plug.

I agree with @zheka757 . I won't buy frags that haven't started to encrust. They do much better if they're allowed to heal in the tank they grew in. JMO

I got a few of them and some of them just took off and encrusted out the whole plug in like 2 weeks. This one I guess won't but I'm kind of worried about the pattern here. I've seen RTN/STN and usually it's just white like all the flesh is gone, it looks different here like the skin is being eroded away.
