I think those are the same.
Looks like they've copied the Arcadia ArcTanks here. Same design and trim with the clear moulded corners and glass lid.
P@H have just got the ArcTanks in if you want to get a close up look at these tanks. I noticed 1 in there the other day when I had a look to see if they had any striking Mopani (always worth a gander) and they look quite cool.
In August I saw them on Charterhouse and was thinking about buying one of these in March to setup as a small living room tank but then decided to move house and now my existing tank is going in the living room, so maybe in the future. lol
The one thing I like about the Arc Tanks though is the ArcPod included which makes the tank look quite cool.
