My guess and personal opinion is, while I like most of our LFS's, it is very difficult to shop at Coral Corral. The fact that they run their actinic lighting only during operating hours and you must look top down at corals in tubs through often not so clear acrylic is difficult and discouraging.
Yes I know they will turn on the whites if you ask, but if they're busy helping other customers I end up walking out. Don't get me wrong though, I do like the staff and the place is clean and huge with awesome display tanks. But I want to really see what I'm buying first.
Also, their social media presence is almost non existent compared to the others mentioned. Many times I saw a fb post and headed down to their store to check out what they got in.
