There are many colorful fish that are popular choices for home aquariums. The wide variety of bright colors and interesting behaviors make these fish appealing for aquarium hobbyists. When setting up a new tank, people often want to include fish that will add vibrant colors and visual interest. But what exactly are these fish called? There are a few common names used to refer to colorful aquarium fish.
Some key facts about colorful aquarium fish:
– They come in a huge range of bright colors like red, orange, yellow, blue, purple, etc. This makes them stand out in an aquarium.
– Certain species are known for having striking color patterns, such as stripes, spots, or bands of contrasting colors.
– While some fish are naturally colorful, others develop more vibrant colors when kept in optimal tank conditions.
– Colorful fish help add diversity and beauty to aquarium displays. They are popular choices among freshwater and saltwater fishkeepers.
– Examples include bettas, guppies, cichlids, danios, angelfish, discus fish, and many types of tetra.
So what terms are commonly used to describe these fish? There are a few options:
Tropical Fish
One broad category is tropical fish. A tropical fish is any fish species that originates from tropical waters around the equator. The warm, stable temperatures in these regions enable fish to develop bright, colorful markings.
When we think of a classic aquarium fish, a small, vibrantly colored specimen like a neon tetra or guppy often comes to mind. These fish are natively from tropical areas like the Amazon River basin in South America.
Other popular examples of tropical fish include:
– Bettas – Known for their long, flowing fins and variety of colors like red, blue, and purple. Native to Asia.
– Discus – Disk-shaped fish with captivating patterns of yellows, blues, reds, and browns. From the Amazon River.
– Oscar – A larger cichlid species with an orange/red/black coloration. Native to South America.
– Zebra danios – Active schooling fish with stripes reminiscent of zebras. From South Asia.
The term “tropical fish” is a fitting description for these fish and many others that aquarium hobbyists value for their bright colors and lively activity. Calling them tropical fish highlights their origins and care requirements.
Freshwater Fish
Another broad category is freshwater fish. As opposed to saltwater fish, freshwater fish live in rivers, lakes, ponds, and other bodies of water with very low salinity levels. Most home aquariums contain freshwater fish.
Some examples of colorful freshwater fish include:
– Neon tetras – Small schooling fish with an iconic blue and red striped pattern. From South America.
– Guppies – Extremely colorful fish that can display any combination of red, green, blue, orange, black, purple, yellow, etc. Originally from northeast South America.
– Mollies – Plump-bodied livebearers that often have yellow, black and white coloration. From Central America and Mexico originally.
– African cichlids – A highly diverse group of cichlids from Africa’s Rift Valley lakes. Many have bright color patterns.
– Rainbowfish – Long-bodied fish named for their brilliant colors reminiscent of rainbows. From Australia and Southeast Asia.
While tropical fish are a subset of freshwater fish, the term “freshwater fish” also includes fish from more temperate regions that can still provide quite beautiful colors, such as koi and goldfish. So “freshwater fish” covers both tropical and temperate zone species.
