I may be wrong, but those acros look wild/maricultured. I have not had much luck with those. Not that you won't, but they seem to die in about two months for me. I figure they had trouble adapting from natural sunlight and saltwater to my artificial reef. So if they die don't be to hard on yourself and try some true aquacultured acros. Like I said, they may do fine in your tank, maybe it is me.
