A desktop aquarium adds natural beauty and life into any office, dorm room or apartment. Desktop aquariums are 10-gallons or less and generally used to house small freshwater fish. Even with their small size, they can still be beautifully decorated with pieces of driftwood, small stones, artificial or live plants and/or aquarium safe décor.

It's important to note that tanks less than two gallons should be avoided since they are harder to maintain, and there are very few creatures that can live in such a small environment. A desktop aquarium can still be low maintenance if you don't overfeed the fish or overstock the tank. The one inch per gallon rule helps to determine the number of peaceful community fish (up to two inches) you can keep in your tank. If you have a local pet store in your area that specializes in aquariums, try taking a visit there since they often have fish and supplies that are harder to find. People who work at local fish stores also tend to have more experience in the hobby than those at Petsmart or Petco. Here are the top ten easiest and most beautiful fish for a desktop aquarium.

1. White Cloud Mountain Minnow

White Clouds have a silvery white stripe down their lateral line and red fins and grow to be about 1.5 inches. They prefer cool waters, 64°-72°F (18°-22°C) with a pH between 6.5 and 7.5. They can live in tanks as small as five-gallons and don't require a heater. White Clouds also prefer a strong current, so a sponge filter isn't the best option. They will readily accept most flakes, micro pellets and freeze-dried foods available for small community fish.

2. Betta/Siamese Fighting fish

Bettas are a super popular beginner fish that can live in just a gallon of water. They don't require aeration because they have a labyrinth organ that allows them to take in air when the dissolved oxygen level is low. Bettas come in a rainbow of different colors and a wide variety of tail patterns from veil tail to crown tail to Twin Tail. They require warmer waters between 75° and 86°F (24°-30°C) with a pH between 6.0 and 8.0. Male Bettas should be kept alone, without any tank-mates, if they are in tanks less than 10 gallons. Female bettas can be kept in groups of odd numbers if they are in a tank over 5-gallons. Male Bettas also shouldn't be kept in the same tank without a divider (hence the name Siamese Fighting Fish). They are carnivores and should be fed pellets and occasionally freeze-dried brine shrimp or bloodworms.

3. Endler's Livebearer

The Endler's livebearer is a very colorful and tiny tropical fish that can thrive in a small aquarium. Endler's livebearers look like guppies, but smaller, only growing up to an inch long. These fish come in a variety of brilliant colors and patterns, ranging from red to neon green or yellow with cobra pattern. They can live in water temperatures from 64°- 82°F(18°-28°C) with a pH between 5.5 and 8.0. Endler's livebearers are omnivores and should have a diet of flakes and freeze-dried bloodworms, tubifex, or brine shrimp.

4. Chili Rasbora

The Chili Rasbora is an easy-to-keep fish that displays a brilliant ruby red color with a black stripe. Chili Rasboras are schooling fish that should be kept in groups of five or more. Since they only grow to a little under an inch, they are suitable for really small tanks. Chili rasboras prefer temperatures from 68°-82°F(18°-28°C), pH from 4-7 and low water flow-since they are so tiny. They accept micro-pellets, crushed flakes, and baby brine shrimp or cyclopods.

5. Sparkling Gourami

The Sparkling Gourami is another beautiful yet hardy fish for a small tank. These fish have a golden body with specks of iridescent red and fins with blue and green spots. Like bettas, they are a Labyrinth fish and do fine in lower dissolved oxygen levels. These fish grow to be about 1.5 inches. They prefer temperatures between 77 °F and 83 °F (25 °-28 °C), a pH between 6.0 and 7.5 and lots of plants. Sparkling Gourami should be fed algae-based flake foods along with freeze-dried bloodworms or brine shrimp.

6. Japanese Ricefish/Medaka

Japanese Ricefish are creamy white or creamy orange in color. They can live in cooler water from 64° to 72°F and are very adaptable to different water parameters. They grow to be about 1.5 inches long and will accept a variety of dry and frozen foods as well as vegetable matter. They prefer densely planted tanks.

7. Fancy Guppy

Fancy guppies are very popular for small aquariums. They grow to be two inches long come in a very wide range of colors, from purple to lemon yellow to red to cobra etc. Fancy guppies should be kept in a tank of at least five gallons with water temperature 64-82° F, and pH 5.5-8.0. They will readily accept flakes, micro-pellets, and freeze-dried bloodworms, tubifex, or brine shrimp. Guppies are also relatively easy to breed.

8. Rosy Loach

Rosy loaches grow to be between one and 1.5 inches long. Males are light pink/peach in color and females are grey with a black stripe. They can be kept in tanks as small as three gallons with a temperature of 68-78°F and a pH from 6-8. Rosy loaches prefer to be kept in planted tanks. They can be fed sinking pellets or tablets and occasionally some daphnia, blood worms, or brine shrimp.

9. Clown Killifish

Clown Killifish have iridescent eyes (under the right lighting), yellow and black vertical bars and a blue and red striped tail. They should be kept in a tank that is at least five gallons. A lid is highly recommended since they are jumpers. The water temperature should be between 73 and 79° F and a pH between 6.0 and 7.5. They prefer brine shrimp and tubifex, but will also accept flake foods.

10. Pygmy cory catfish

While catfish are not a good option for small tanks, the Pygmy Cory is an exception. They have a stripe that runs the length of their body and grows to be only an inch long. Pygmy Cories prefer to be in groups and should be kept in a tank with a sandy substrate for them to sift through. The water temperature from 72-79°F with a pH between 6.4 and 7.4. They will accept a diet of sinking pellets and freeze-dried foods.

In our patriarchal society, men hide from their feelings, but toxic masculinity is literally killing men. They swallow the pain and move on so that they can look, feel, and act "tough."

But, strength is derived from asking for help and voicing your struggle and, trust me, working on your mental health is one hell of a struggle. The real way to "man up" is to acknowledge the downfalls in unjust societal norms. Mental health problems do not mean that a man is weak, they are neurologically-based disorders that require professional treatment.

Sorry, But 'I Don’t Care About Politics' Is Not A Valid Excuse For NOT Voting

The younger generation of voters is so crucial to the upcoming election because our vote is going to shape the world that we are about to enter as adults.

27710

When I ask my friends if they are voting this term most of them respond with "no" followed by an explanation of "I don't care enough," "It doesn't affect me," or "I don't keep up with politics," etc. I get it, as a college student I know that there are many other things to be concerned about like school, relationships, work, and friends. I also understand that keeping up with politics can seem like trying to keep up with an over-exaggerated reality show that has way too many seasons. Not to mention most news stations and websites are biased so it's hard to decipher if what you hear is true or fake.

However, despite all of this annoyance, as the next generation of Americans, we have to remember that we owe it to ourselves, our families, and to our futures to care.

Two of my favorite things in life are reading and books. Obviously, they go hand-in-hand. In my life, I've realized that there is nothing better than learning about the current world or getting fully immersed in another world. Reading can inspire, teach, and entertain you.

For me, the feeling of opening a book and smelling that fresh book smell can't compete with anything else.

20 Books About Latin And Hispanic Heritage Absolutely Everyone Should Have On Their Bookshelf

Any ally of the community needs to be reading these incredible reads.

I go through phases when it comes to what I like to read. I am typically reading two books at any given time: one serious nonfiction and one escapist fiction novel to have on hand and open up depending on my mood.

What remains consistent, however, amongst most of my fellow bibliophiles is a desire to try new and different authors and genres. I, as an Indian woman, have been partial to reading books written by fellow Indian and Desi writers since I first got a library card.

It's 2020, where change is inevitable and norms are not only questioned, but challenged.

We live in a world where it's become customary to push boundaries, break rules, and question standards upheld by society. Though try as we might, some of these standards are harder to conquer than others — body image is one of the top contenders.

For years, the body positivity movement has pushed for the acceptance of all marginalized body types not represented or celebrated in the media. Recently, we've gotten better at appreciating and accepting all body types, but one thing that's still lingering is the stigma of body image in the fashion industry — more specifically, the term "plus-size."
