Setting up a community aquarium is like curating a little slice of tranquility in your home. But let’s be honest: not all fish get along swimmingly. The trick is to find species that won’t turn your peaceful tank into a battleground. Lucky for you, I’ve rounded up my top picks for the most peaceful community fish that will keep the vibes in your aquarium nothing but chill. Let’s dive into it!
1. Neon Tetras
Neon Tetras are the superstars of the community tank world. These tiny, colorful fish with their striking blue and red stripes are not only easy on the eyes but also super laid-back. They’re schooling fish, so they’re happiest in groups of six or more. Their small size and peaceful nature make them perfect tankmates for a variety of other fish. Plus, they thrive in slightly acidic to neutral water with a temperature range of 70-81°F, which is pretty standard for many community tanks.
2. Guppies
Who doesn’t love guppies? With their rainbow of colors and lively personalities, guppies are like the social butterflies of the aquarium. They’re hardy, adaptable, and get along with most peaceful fish, making them an excellent choice for beginners. Just a heads-up, though: they breed like crazy! So unless you want a guppy explosion, it’s a good idea to keep only males or maintain a balanced male-to-female ratio. Guppies do well in a variety of conditions but prefer water temperatures around 72-82°F.
3. Corydoras Catfish
Corydoras Catfish are the perfect little cleanup crew for your tank. These bottom-dwellers are known for their peaceful temperament and hard-working nature, as they spend their days scouring the substrate for leftover food. They’re also super social and thrive in groups of five or more. Corydoras come in a variety of species, each with their own unique look, but all share the same easygoing nature. They prefer a tank with a soft substrate and plenty of hiding spots, along with water temperatures around 70-78°F.
4. Harlequin Rasboras
Harlequin Rasboras are another fantastic option for a peaceful community aquarium. Their shimmering orange bodies and distinctive black triangle markings make them a beautiful addition to any tank. They’re schooling fish, so keep them in groups of at least six to see their best behavior. Harlequin Rasboras are easy to care for, adaptable, and thrive in water conditions with a pH of 6.0-7.8 and temperatures between 72-81°F. They get along well with most other peaceful fish, making them a great all-rounder.
5. Platies
Platies are bright, cheerful, and come in a dazzling array of colors and patterns. They’re hardy fish that do well in a variety of water conditions, which makes them perfect for beginners. Platies are also livebearers, which means you might end up with some fry if you have both males and females in your tank. They’re peaceful by nature and get along well with other small, non-aggressive fish. Aim for water temperatures around 70-82°F, and you’ll have some happy platies swimming around.
6. Cherry Barbs
Cherry Barbs are a great pick if you’re looking to add a splash of red to your tank. Unlike some of their more aggressive barb cousins, Cherry Barbs are mild-mannered and get along well with other peaceful fish. They enjoy being in small groups and are very active swimmers. Males have a vibrant red color, while females are more of a subdued pink, but both are lovely additions to a community setup. Cherry Barbs prefer slightly acidic to neutral water with temperatures between 73-81°F.
7. Mollies
Mollies are like the easygoing cousins of the guppy—they’re versatile, hardy, and come in a variety of colors and shapes. Whether you go for the classic Black Molly or the more exotic Sailfin variety, you’re in for a treat. Mollies are generally peaceful, though they do best in slightly larger groups. They thrive in a range of water conditions, including slightly brackish water, but prefer temperatures around 72-82°F. Just like guppies, mollies are prolific breeders, so plan accordingly!
8. Dwarf Gouramis
If you’re looking for something a little more unique, Dwarf Gouramis might be the fish for you. These stunning fish come in vibrant blues, reds, and everything in between. They’re generally peaceful and make a great centerpiece fish for community tanks. Dwarf Gouramis do well with other small, non-aggressive fish but can be a little shy, so provide plenty of hiding spots. They prefer slightly acidic to neutral water with temperatures around 77-82°F. Just keep an eye on them, as males can sometimes be territorial with each other.
9. Kuhli Loaches
Kuhli Loaches are like the little ninjas of your aquarium. These eel-like fish are super shy but incredibly peaceful, spending most of their time hiding under rocks or burrowing in the substrate. They’re best kept in groups of three or more and do well in a tank with plenty of hiding spots. Kuhli Loaches are excellent tankmates for other peaceful fish, as they keep to themselves and help clean up the bottom of the tank. They thrive in slightly acidic to neutral water with temperatures between 75-86°F.
10. White Cloud Mountain Minnows
Last but not least, White Cloud Mountain Minnows are a great choice for cooler water community tanks. These tiny fish are hardy, peaceful, and do well in groups of six or more. They have a subtle but beautiful coloration, with a shimmering body and a touch of red on their fins. White Clouds are very tolerant of a wide range of water conditions but prefer temperatures on the cooler side, around 64-72°F. They’re perfect for a low-maintenance, peaceful tank setup.
