CENTRAL COAST AQUARIUM in California has been jumping lately as visitors come through to get a selfie with Joan, a color-changing octopus accidently caught by a fisherman and then taken in by the aquarium. You might not have access to eight sucker-lined arms to pull in customers, but you can house exotic and colorful fish in your aquariums, which should fall into some of these trending categories.

Nano Setups

Nano is very now, and these small and stylish tanks are ideal for beginning aquarium hobbyists. In one armload, you can send a fish owner home with a head-to-toe setup, minus the headache of all the filter and water conditioner choices. The set-up is just as easy. Once the buyer is home, he can create a stunning piece of decor in a snap.

All in One

All-in-one kits continue to be popular with customers looking to get started or treat themselves to a whole new system without picking out all the plants, hardware and potions. All-in-ones can work for kids, but the real money is in curious adults and active fish keepers willing to spring for a replacement tank or use their tax refund to splurge on a new setup.
