An Ocean-Approved "Finding Nemo" Tank

We're here to help you re-create the dentist's fish tank as spot-on as possible. To start, pick up a volcano bubbler and the tiki-heads-and-plants combo from Amazon.

Amazon only sells a diver in a black suit, but it comes attached to a bubbling treasure chest, which is also a pretty big part of the tank.

You'll also want a diver's helmet for your fish to rest in, like Nemo does. Then add some familiar character ornaments. Sadly, they don't seem to sell the original "Finding Nemo" cast anymore, but you can pick up the "Finding Dory" cast.

There are Fish in Here

Finally, what better way to tell people there are fish in your fish tank than to literally spell it out for them?

Hashtag Ornament ($3.99)

But, it's not enough to just have the one meta decoration. Complete the obvious theme with a "no fishing" sign, some fake fish ornaments, an ocean backdrop and, the pièce de résistance, a live fish sticker with arrows pointing to your very live fish.
