They come in a variety of colors, including black, silver, and even vibrant marbled patterns.
Ideal for community tanks, angelfish are generally peaceful but can exhibit territorial behavior, especially during breeding. When introducing them to your aquarium, ensure that their tank mates are compatible; ideally, select other peaceful freshwater fish that can coexist without stress. A well-planted tank is essential for zone distribution, allowing angelfish to establish their space without conflicts.
Freshwater angelfish thrive in water temperatures between 76-82°F and appreciate soft, slightly acidic water conditions. Regular maintenance, including water changes and proper filtration, is crucial to keep them healthy. Understanding their needs and respecting their space will lead to successful angelfish care.
2. Freshwater Guppies - The Color Splash

Known for their playful nature, guppies are schooling freshwater fish that thrive in groups. They are easy to breed and can live in a variety of freshwater fish habitats, making them a great choice for novice hobbyists. To maintain their health, provide a balanced diet, including high-quality flakes and occasional treats like bloodworms or daphnia.
Caring for guppies also includes maintaining a stable water environment with a temperature around 74-80°F.

These stunning freshwater fish are outgoing and assertive, often standing out in any aquarium setting. Bettas come in numerous color variations and tail types, each displaying unique and exquisite beauty.
While they are often kept solo due to their aggressive nature, male bettas can sometimes coexist with peaceful freshwater fish. They do best in tanks with gentle filtration and require warm water temperatures of around 75-80°F. Special care should be taken to avoid stressors like overcrowding or aggressive tank mates, which can lead to health issues.
Caring for bettas includes maintaining water quality, providing hiding spots for security, and ensuring a balanced diet. They thrive on high-quality pellets and occasional live foods, which can enhance their colors and vigor. When properly cared for, bettas can become stunning focal points in your aquarium.

These small fish, only around an inch long, are perfect for creating a lively community tank. Their shimmering colors make them visually appealing, especially in a well-planted aquarium that provides a natural habitat.
Neons prefer to school with their own kind, so it's recommended to keep them in groups of six or more. This behavior not only helps them feel secure but also showcases their vivid colors effectively. They thrive in acidic water, around 70-81°F, which aligns with many tropical freshwater fish environments.
Ensuring proper care for neons involves providing adequate filtration and avoiding overfeeding, which can lead to health problems.
