I am pretty sure Rob originally owned Aquatica. I was going there when he first opened, it was only him running it without help.. It was small, only one unit with the shark pond, fish on the left, corals on the right. He opened the place after leaving his partnership with Barrier Reef on Archer ave, in Chicago. To be honest, I was buying from Rob for a year, and visiting at least once a week. I never saw Mario once, he must have partnered later. All in all, Rob was a super cool dude, I'm gonna go check his place out today.
