Research and Education: Before getting any fish, educate yourself about different freshwater fish species. Learn about their size, behavior, diet, and compatibility with other fish.
Start with Hardy Species: As a beginner, it's wise to choose fish that are hardy and adaptable to a beginner's mistakes.
Check Compatibility: Some fish can be territorial or aggressive, while others are more peaceful and social. Research the compatibility of fish species before adding them to your tank to prevent conflicts and stress.
Maintain Water Parameters: Different fish species have varying water parameter requirements (temperature, pH, hardness). Choose fish that have similar needs to make maintenance easier.
Consider Tank Size: Choose fish that are suitable for the size of your aquarium. Larger fish need more space to swim, while smaller tanks are better suited for small and peaceful species.
