I never used the ocean theme in my creations but the aquarium boosts my imagination for sure. I have a beautiful one at home and at nights, when I work, I can get my mind into another galaxy by watching it. The aquarium is like a portal. For the offices an aquarium is great, everyone loves staring at it. This doesn't mean that all the aquariums worth the attention, I saw a few ugly ones. I got influenced by https://arcreef.com's articles and put some time and effort to make mine a good source of inspiration.
