An aquarium is a magical world that can transform any space into a peaceful and vibrant corner. However, choosing the right fish is essential for maintaining the balance and harmony of the aquatic ecosystem.

If you're wondering, "What fish should I put in my aquarium?", you're in the right place. Below you'll find a complete guide to the best fish options, based on the catalog of Aquariumshop.gr.

Choosing Fish by Type

Freshwater Fish

If you're planning to set up a freshwater aquarium, there are many interesting fish species to consider:

• American Cichlids: These colorful fish can be quite aggressive and are more suitable for experienced hobbyists.
• African Cichlids: If you're looking for vibrant colors and dynamic behavior, cichlids from Lake Malawi and Lake Tanganyika are an excellent choice.
• Catfish: Ideal for keeping your tank clean, as they feed on food leftovers and algae.
• Labyrinth Fish: Such as the striking Gouramis and Trichogaster, which can breathe atmospheric air, making them perfect for smaller tanks.
• Schooling Fish: Tetras, Hyphessobrycon, and Barbs are peaceful fish that move in groups, creating a beautiful visual effect.
• Livebearers: Fish like Poecilia and Platy give birth to live young and are great for beginners.

Saltwater Fish

If you choose a saltwater aquarium, you'll have access to impressive and exotic species:

• Angelfish: Majestic fish with striking colors and elegant movement.
• Tangs: Known for their vibrant colors, such as the famous Blue Tang from the movie Finding Nemo.
• Wrasses & Dartfish: Fast and energetic fish that add liveliness to your tank.
• Dragonets: Like Pterosynchiropus, with bright colors and unique behavior.
• Butterflyfish: Graceful fish with unique shapes and vivid hues.
• Triggers: Bold and lively fish, typically recommended for more advanced aquarists.
• Dottybacks: Small but brave fish, ideal for smaller saltwater tanks.

How to Choose the Right Fish

Choosing the right fish depends not only on their appearance but also on several important factors:

1. Tank Size – Small tanks require species that don’t grow too large, while bigger tanks can host more demanding fish.
2. Compatibility – Some fish are more aggressive and may not coexist well with peaceful species.
3. Water Conditions – Whether freshwater or saltwater, temperature, pH, and hardness affect your fish choices.
4. Diet – Some fish are herbivores, others carnivores, and some omnivores. Choose species whose dietary needs you can meet.
5. Experience Level – If you're a beginner, go for easy-care species like livebearers. If you're experienced, try more demanding fish such as cichlids or saltwater species.

Tips for Introducing New Fish to the Aquarium

To ensure a smooth transition for your new fish:

• Acclimate them slowly to the tank’s temperature and water chemistry.
• Don’t add too many fish at once to avoid sudden changes in the ecosystem.
• Provide a balanced diet.
• Observe their behavior for any signs of stress or illness.
