I saw the Oceanic Illuminata at Aquatek. I had to take multiple looks at it. I also like the rimless look. The negatives though: it is too tall for my tastes and the width / depth is only 18". If it was at least 24", I think it would catch on quick. Also don't remember correctly, but I don't think it had the high clarity glass, but could of been wrong.
Overall nice looking tank but would change the dimensions.
I've never personally owned a glasscages tank but I've heard good things about them related to being solid. The only negatives I've heard is the silicone finish quality. I don't mind some extra silicone when it comes to gallons of water in my house! They also have great dimensions to pick from.
