The best low-maintenance fish to keep you company in your office

Are you looking for a conversation piece for your office? Consider buying a fish. They are low-maintenance office pets. They’re relaxing to watch and invite more conversation than a houseplant. 

If you work in a cubicle or only have a small amount of space to devote to a fish, consider one of these varieties. As long as you feed them regularly and keep their tank clean, they’ll provide hours of enjoyment for you and anyone who visits your office during the workday.

Meanwhile, if you’re seeking out impressive species for your house and you want a truly jaw-dropping conversation piece, check out small sharks for home aquariums

Betta (Siamese Fighting Fish)

Sporting brilliant colors and an attitude, the betta makes a bold statement. These beautiful fish are extremely aggressive and do best when they are the only fish in the bowl. Even so, they are extremely low-maintenance and provide a display of color and majesty as they swim through the water.

Betta fish originate from Thailand where they live in shallow marshes, flood plains, and rice paddies. Their life expectancy is three to five years.

Guppies come in a variety of colors — even neon. They are one of the several varieties of fish that harmonize with bettas quite well. Their colorful tail fins come in a wide variety of colors and shapes. You can keep several together in a large bowl; however, if you don’t want a bunch of baby guppies, make sure you buy only males. 

These inexpensive fish are very energetic, especially around feeding time, and only require clean water and as much food as they can eat in 20-40 seconds once or twice a day. Native to South America, there are nearly 300 varieties of guppies. Their average lifespan is approximately two years.


Mollies are a collection of three species of fish originating from the Southeastern United States, the Gulf of Mexico, South America, and Central America. They come in a variety of colors and have an average life expectancy of one and a half years. 

Like guppies, these livebearing fish will produce a lot of offspring, so consider buying males if you don’t want to deal with babies. They do best in a well-planted tank with a sandy bottom where they can search for food.

Endler’s Livebearers

Endler’s Livebearers are a smaller version of the guppy that grow to a length of 1 inch. Their vibrant colors are displayed in striking patterns, and many have a double sword tail. They love a habitat filled with plants and other secluded places to hide. 

These hardy, livebearing fish originate in Venezuela, and as schooling fish, do best in groups of three or more. Their average lifespan is two to three years.

White Cloud Minnows

These small, peaceful fish only grow to a length of 1.5 inches and can live up to seven years. Due to their timid nature, they prefer to have plants and other hiding areas in the tank. They are school fish and are happiest in groups of five or more.

White cloud minnows are native to the Pearl River in China. Common varieties are silver and green with iridescent pink stripes. They have big appetites, and even though they will feed on the algae in your bowl, must be fed a diet of live prey (water fleas and brine shrimp), greenery (green algae), and flake or pellet food twice a day.  

Pygmy Corydoras

These friendly little catfish only reach a length of 1 inch that like sandy gravel and lots of plants in their habitat. These peaceful fish, native to the upper Rio Orinoco basin in Columbia and Venezuela, are easy to care for. They have a lifespan of three years. 

Because they are school fish, it’s best to keep them in groups of four or more. They swim very close to the ground, digging for leftover food in the sand. 

Neon Tetras

Originating in the Amazon basin of South America, neon tetras are brilliant little flashes of red and blue color which usually don’t grow much longer than 1.5 inches. Although they are hardy fish once they’re established in the tank, they are very susceptible to changes in their environment and are the most delicate during the first week.

These peaceful fish like to travel in groups, so plan to add several in your tank. They eat twice a day and have an average lifespan of 10 years.

Cherry Shrimp

Freshwater cherry shrimp are a colorful and unique alternative to owning traditional fish. Since they don’t produce much waste, you can keep as many as 20 in a 5-gallon container. Native to the streams and ponds in Taiwan, they are happiest in a densely planted tank where they can hide and nibble on the algae and moss. Cherry shrimp are active day and night but only live for one to two years.

Harlequin Rasboras

Rasboras are schooling fish that are closely related to goldfish and koi. Dwarf emerald rasboras are perfect for small office tanks. Because they are school fish, plan to purchase several together so they feel safe. Four is the limit for a 5-gallon tank.

These peaceful, colorful fish originate from southeast Asia where they live in forest streams and floodplains. Their metallic silver and orange fins are eye-catching, and they can live as long as six years.

Enjoy the adventure

Research indicates having an office fish tank reduces stress, lowers blood pressure and anxiety levels, and can even improve your sleep quality. And, thanks to the recent popularity of the hobby, you can easily find aquatic kits of every size at your local pet store. Have fun choosing the right tank and fish to fit your space and personality!

What do painted turtles eat? This is the only feeding guide you’ll need
Find out what to feed them and what not to feed them
Painted turtle eats a mealworm

You bring home a little turtle to a beautiful habitat and realize you forgot one big thing: What do painted turtles eat? Because these turtles are an aquatic species, they spend most of their time in the water — both in the wild and in your house. This greatly impacts their diet, especially because as they consume meals, they must swallow under the surface.

Painted turtles are also omnivores and like a wide variety of foods. While many of these can be placed in their housing, you should also have a separate feeding tank, which will massively cut down on the mess. All food from the main tank will have to be scooped out daily; otherwise, it rots. Nevertheless, feeding your turtle can be fun, and occasionally they can even eat what you do.

Try these 3 techniques to lower pH levels
Man working on aquarium

Keeping your pH consistent is a major part of a thriving aquarium. Too high or too low, and your whole ecosystem will be thrown out of whack. Generally speaking, the acceptable pH levels for an aquarium range from 6.8 to 7.8, with 7.0 being the neutral point. (Keep in mind your tank’s acidic or alkaline levels will go up and down pretty regularly, too.) What causes high pH in an aquarium? Here's the key information you need to know.

What is pH in Aquariums?
If you barely remember high school chemistry, you might be a little unclear about what pH even means and why it matters to your fish. First, know that we're actually looking at a measurement, which indicates the level of acidity or alkalinity of a liquid. Lower numbers mean more acidic and higher numbers, less.

Can I get a shark for my fish tank?
Yes, but they have stringent requirements and experts often recommend leaving shark caretaking for advanced hobbyists or professional aquariums. However, if you decide you're up to the challenge, you should prep first. A lot. The general rule of thumb says that the tank needs to be more than three times the length and two times the width of the (biggest) adult shark.
