When it comes to picking fish for a low maintenance tank, smaller is usually better. Large fish tend to have higher care needs and create more waste. You’ll also want to avoid aggressive fish that may fight or pick on more peaceful tank mates. Hardy fish that are not sensitive to water conditions are best for beginner aquarists.

Here are the top 10 best fish for low maintenance aquariums:

Betta Fish

Betta fish, also known as Siamese fighting fish, are one of the most popular fish for beginner aquarists. These brightly colored fish can thrive in relatively small tanks and do not require strong water filtration or heating. Male bettas must be kept alone due to their aggressive tendencies towards other male bettas. Females can be kept in groups in larger tanks. Bettas mainly require clean, still water to remain healthy. Their unique labyrinth organ allows them to breathe air directly from the surface.

Platies

Platies are small, peaceful fish perfect for community low maintenance tanks. Their bright colors and active nature make them fun to watch. As livebearers, platy fish enjoy harder water conditions and do not require special care. They help keep algae under control in the tank and can be kept in groups of 2-6 fish. Mix males and females for breeding. Platies are hardy, can adapt to a range of water conditions, and eat both flake and freeze-dried foods.

Zebra Danios

Tiny zebra danios are a go-to choice for beginner community tanks. Their horizontally striped pattern makes them a standout. These active schooling fish should be kept in groups of at least 6. Zebra danios are very hardy, tolerate a wide temperature range, and are not picky eaters. They help liven up the tank but don’t add much to the bioload. These fish may even breed on their own if kept in a species-only tank.

White Cloud Mountain Minnows

Like zebra danios, White Cloud Mountain minnows are tiny hardy fish perfect for small low tech tanks. They tolerate a wide range of water parameters which makes them extremely low maintenance. Their gold and red coloration provides nice contrast against lush planted tanks. White Clouds shoal together peacefully and combine well with other community fish. These minnows are also prolific breeders if given the right environment.

Neon Tetras

The bright colors of neon tetras make them instantly recognizable. Their glowing blue and red stripes light up any aquascape. As schooling fish, they should be kept in groups of at least 6. Neons are peaceful mid-level tank dwellers. They adapt well to standard tropical community tank water parameters and standard lighting. Neons mainly subsist on flake foods and live foods. Their small size also helps reduce waste. When kept in the proper conditions, neons can live up to 10 years.

Guppies

No low tech tank is complete without a few guppies. These classic aquarium fish add tons of color with their elaborate tails and vivid patterns. Guppies are extremely hardy and unfazed by fluctuating water conditions. They are livebearers that enjoy harder alkaline water. Mix males and females for breeding; the fry can also serve as food for larger tank inhabitants. Male guppies in particular are low maintenance since they are smaller and have shorter finnage than females.

Corydoras Catfish

For the bottom level of the tank, consider adding a small group of corydoras catfish. There are many color variations of cory catfish available. Though they spend most of their time scavenging along the substrate, their active nature and armored exterior makes them fun to watch. Cories have small mouths and do not disturb plants. These peaceful fish help clean up excess fish food and debris that settles. They thrive in schools of 6 or more catfish.

Cherry Barb

The bright red coloration of male cherry barbs provides superb contrast against most aquarium backdrops. Females are a more muted silver with hints of red in the fins. Cherry barbs are energetic schooling fish. They should be kept in groups of 5-7 barbs or more. Cherry barbs are very hardy, can tolerate a range of water parameters, and are not picky eaters. Their small size and low bio-waste output also makes them suitable for nano tanks.

Bristlenose Pleco

For algae control, add a bristlenose pleco to your low maintenance community tank. These small bottom dwelling fish consume large amounts of algae. Their size maxes out around 5 inches, making them a great option for smaller tanks. Bristlenose plecos are peaceful, hardy, and undemanding. They do appreciate having driftwood in the tank to graze on. Make sure to supplement their diet with sinking algae wafers as needed.

Mollies

Last up are mollies, another classic livebearing fish. These big-bodied fish come in a variety of colors like black, gold, and white. Dalmatian mollies have an eye-catching polka dot pattern. Mollies prefer hard alkaline water and salt can be added to match their brackish origins. They are very tolerant of water changes across metrics like pH, hardness, and temperature. Mollies are social and should be kept in small groups. They will readily accept most flake and pellet foods offered.

Conclusion

Creating the ideal thriving ecosystem with healthy fish does not have to be complicated or time-consuming! Sticking with small schooling community fish that tolerate a wide range of water parameters is key for low maintenance success. By following the best practices for the fish species you select, anyone can enjoy the relaxing hobby of fishkeeping without the major hassle. Set up a simple, sparse aquascape for them, feed a varied diet, change water periodically, and let the fish do the rest.
