Those pictures look great... No telling who took them, when, and under who's care they were under at the time of the pics. Long story short those pics are NOT necessarily representative of the livestock/husbandry of Aquacon. And TBH that goes for most all sites. Unless you get a WYSIWYG photo you can be sure the sites choose the prettiest most actinic flooded example of a nem/coral/eyecandy they can find. Even with WYSIWYG photos be aware of the lighting situations that the pics were taken under.
