Live aquatic plants don’t just make tank look beautiful, they also improve fish water environment. Aquatic plants help absorb nutrients, prevent algae growth, provide oxygen, hiding spots where fish can relax. Whether you’re just starting or changing your aquascape, here are some of the best aquarium plants that are easy to care for and thrive in most freshwater setups.

1. Java Fern

• Light: Low to moderate
• CO₂: Not required
• Placement: Attach to driftwood or rocks. Java Fern is a favorite among keepers because it’s fresh, low-maintenance, and grows slowly. It doesn’t need substrate, you can tie or glue it to wood or stones, making it great for beginners and betta tanks.

2. Anubias

• Light: Low to moderate
• CO₂: Not required
• Placement: Midground or attached to decor. Anubias is tough plant that’s nearly impossible to dead. Its broad, dark green leaves provide hiding spots for fish like bettas, and it grows slowly with minimal care. Just don’t bury its rhizome!

3. Java Moss

• Light: Low
• CO₂: Not required
• Placement: Attach to wood, rocks, or float freely. Java Moss is good for shrimp tanks and fry tanks. It provides a place to collect biofilm and helps baby shrimp survive. Plus, it’s flexible, you can grow it as a carpet, a wall, or let it float naturally.

4. Hornwort

• Light: Moderate
• CO₂: Not required
• Placement: Floating or anchored. Hornwort is a fast-growing, floating plant that helps prevent algae by competing for nutrients with algae. It’s great for breeding tanks that provide place for a couple of fry or shrimp. Be prepared to trim it often!

5. Amazon Sword 

• Light: Moderate to high
• CO₂: Optional but helpful
• Placement: Background plant. Amazon Swords are big with a lot of leaves that add a bold, jungle-like look to your tank. They need root tabs or nutrient-rich substrate to thrive, but they’re well worth it for the dramatic greenery they provide.

When most people think every aquarium tank will need a heater but did you know you can keep a beautiful tank without a heater at all? That’s where coldwater fish come in. These species thrive in cooler temperatures, making them perfect for no-heater tank and beginner with a low-maintenance setup

In this guide, we’ll cover what makes a fish “coldwater” and share some easy-to-care-for fish that are perfect for hobbyists of all levels.

What Is a Coldwater Fish?

Coldwater fish thrive well in cool water temperatures between 60–74°F (15–23°C). Unlike other fish, they don’t require heaters to stay warm, which means we can put their tank anywhere we want 

They are often healthy, beginner-friendly, and perfect for smaller tanks, desktop setups, or even outdoor tanks, depending on the species.

Do Coldwater Fish Need a Heater or Filter?

Coldwater fish don’t need a heater, but a filter is essential for any tank to keep the water clean and provide enough oxygen. And it’s also essential to balance ammonia and waste levels safe. And remember not to place your tanks near heaters, windows, or sunlight because sudden temperature changes can stress your fish or kill them.

Conclusion

Coldwater fish is a choice for who looking for a low-maintenance tank and easy-to-care fish. With coldwater fish you can create a colorful, peaceful aquarium that thrives well in cool temperatures. Whether it’s a school of White Cloud Mountain Minnows or a single Goldfish, coldwater fish prove that you don’t need tropical temps to build a beautiful underwater world.

Adding more creatures for your tank, snails might not be the first that comes to mind, but this blog will help you change your mind! Freshwater snails are quiet, helpful, and fun to watch, making them an easy-to-care species for beginners and experienced keepers.

Here’s the reason why adding freshwater snails to your aquarium is a smart move.

1. Algae-Eater, Keep Your Tank Clean

Snails are natural environment workers. They like to eat algae, leftover food, decaying plant matter, and biofilm, helping reduce waste and keeping your water cleaner. While they won’t replace your filter or regular maintenance, they make your job easier. Especially Mystery Snails, Nerite Snails, and Malaysian Trumpet Snails are good at this!

2.Freshwater Snails Are Peaceful Community Members

Most freshwater snails are peaceful and non-aggressive, which makes them great tank mates for most fish, shrimp, and aquatic plants. Cause they like algae, leftover food,… so they don’t compete for food with others, and they’re too slow so they don’t bother anyone else in the tank. Just be sure to avoid some fish like puffers or loaches.

3. Freshwater Snails Are Surprisingly Fun to Watch

Snails are more active than people realize! They often glide along glass surfaces, explore driftwood, graze on leaves, or climb on siphons to reach the surfaces. Each snail has its own behavior and features, and they bring a fascinating vibe to the tank.

4. Super Easy to Care For

The special point about freshwater snails when keeping them is how low-maintenance they are. Because they can rapidly adapt to a lot of water conditions and don’t need moderate lighting or CO₂. Just remember to keep their water clean and give them an extra calcium (cuttlebone or snail foods) to keep their shells strong.

Conclusion

When you’re trying to control algae, create a natural ecosystem, freshwater snails are a great choice. They’re useful, peaceful, and full of personality. So next time you’re at the fish store, don’t overlook these little guys. Your tank (and your clean-up routine) will thank you!
