Little Tanks, Big Opportunity

Nano-aquarium setups can be great for indoctrinating new hobbyists, but only if the pet store selling them provides the right guidance.





The nano concept, as it is employed in the aquatics trade, can be a very good idea. After all, a nano tank is a completely integrated unit with virtually everything that a consumer needs all contained in a single box——minus the fish, of course—which makes for no-muss, no-fuss selling. A retailer can truly tell customers, “This is all you need, except livestock and décor.”

With all of the equipment included, and instructions that make it simple to set up, a nano-tank makes a great aquarium for anyone who is contemplating their very first setup. It does not take up a lot of space, and it is clean, contained and basically foolproof.

Selling nano tanks, however, is far from foolproof.

Complicating things is the fact that many of the nano-aquarium packages on the market today are geared for the marine segment of the hobby. If maintaining a small aquatic ecosystem is difficult in the freshwater realm, it is next to impossible in the marine world. Here, the everything-included concept works well, but the “nano” part does not. Don’t get me wrong, I have seen some fantastic nano-reef tanks; but they are almost exclusively owned by long-time marine enthusiasts who wanted to try a more challenging approach.

If a pet store is determined to make nano-tanks an important element in its aquatic sales, the staff must be on board with the concept. Many marine employees will tell customers that nano-tanks are a bad idea; after all, things can go very wrong very quickly, especially if the customer is not up to the challenge.

Proper education is the key to breeding successful nano-tank customers. This requires time and patience on the part of the store staff, which may have to spend an hour or more making a nano-tank sale. And that’s the proper way to do it. Retailers should strive to make sure that every customer who walks out the door with a nano setup is successful. It’s your reputation on the line if customers fail to achieve success with nano-tanks they purchased at your store. Of course, 100-percent success is not going to be possible, as retailers can never expect everyone to do precisely what they recommend.

One of the biggest challenges to setting up a nano-aquarium is choosing its inhabitants. Selecting livestock for small aquariums requires a really sophisticated understanding of fish species—particularly how large they grow and how aggressive they are. Few beginners have this level of expertise, so if they are going to be successful, they are going to need a good deal of tutelage. With this in mind, retailers must make sure that their employees are up to the task.
There are plenty of marine fish and invertebrates that can do quite well in nano-tanks. Of course, if these are scattered around the marine department, they may be difficult to find. I suggest that retailers select a few tanks that are dedicated to nano specimens. Then, when the time comes, store employees can simplify the process of choosing livestock for nano-aquarium customers by bringing them over to these tanks.

Unfortunately, the vast majority of customers who buy nano-products for marine setups expect to be able to keep anything they want. As soon as they realize how restrictive their choices are, many become discouraged. Others simply choose to pay no attention to the suggestions made by the retailer. They buy what they want, and when disaster strikes—as it almost invariably will—they usually blame the store where they bought the items. To avoid this dilemma, retailers should permit their employees to exercise discretion when they sell marine livestock. This applies to any scenario, but especially to nano-sales.

The fish that are perfect for nano-tanks are not all freshwater, but the vast majority of them are. Bettas can be a good choice, but not the aggressive male/female bubble-nest building species. Instead, focus on the mouth-brooding species that have become more popular recently. Fill a tank with live plants and these fish are easy to maintain. Likewise, there are numerous species of pygmy gouramis and micro-cyprinids that grow no larger than 1 1/2 inches in length.


The very best fish for nano-tanks are members of the killifish family, Cyprinodontidae. There are literally hundreds of these that could easily be kept in 10-gallons of water or less. The problem with killifish is the way they spawn. They lay a few eggs every day, over a long period of time—frequently for months, without taking a break. This makes killifish difficult to culture in large quantities, which is almost a prerequisite for selling a fish commercially. There are, therefore, very few killies sold in pet shops. That is a shame, because they are really the perfect definition of a nano-fish; they stay small, they can live in a tiny environment, they are not aggressive and they are easy to maintain. Retailers that can find a good source for these beautiful little creatures and set up nano-tank killifish displays are almost guaranteed to increase sales of both the setups and the fish.

Made using high-clarity glass, with no plastic frame, Mr. Aqua Mini Bookshelf ( aquariums provide a clean and clear view of aquatic life. Typical aquarium setups use a plastic frame to support and keep the glass from bending under pressure. Mr. Aqua utilizes thicker glass for increased rigidity, along with a specially formulated silicone that bonds the glass together with extreme strength, while still being safe for aquatic life. Mr. Aqua Mini Bookshelf aquariums are available in 1.5-gal., 3-gal. and 6-gal. sizes. Each setup comes with LED lighting and Mr. Aqua Piggyback Filters.




The 5.6-gallon Fluval Spec V, from Rolf C. Hagen (USA) Corp. ( features a modern, upscale design with sleek, black lacquer-like components, etched glass and brushed aluminum trim, creating a minimalist look that blends well with any home décor. A frosted glass top and filter panel conceals the integrated filter and water-circulation system. The Spec V’s adjustable flow control and output nozzles on the circulation pump, and the activated carbon and BioMax inserts of the filter ensure a healthy environment for the fish and helps reduce maintenance. The lighting system features 37 powerful yet energy-efficient 7500K high-luminosity LED lamps set into the underside of a long, narrow brushed aluminum and glossy black arm that stretches across the cover of the tank. The lamps are evenly spaced to illuminate all corners of the aquarium and cast a clear, vibrant white daylight. The etched glass Fluval Spec V aquarium setup also comes with Nutrafin Aqua Plus Water Conditioner and Biological Aquarium Supplement, as well as a low-voltage power supply for increased safety.
