🐠 Fish Compatibility Checker – What It Is and How It Helps

Keeping fish as pets is fun! They are colorful, peaceful, and relaxing to watch. But not all fish can live together in the same tank. Some fish are friendly, while others can be a little bossy or like different water. That’s why we made this easy Fish Compatibility Checker.

🧠 What Is a Fish Compatibility Checker?

A Fish Compatibility Checker is a tool that helps you find out which fish can live together in the same tank without fighting or getting sick. You just choose two fish from the list, and the tool will tell you:

• ✅ If they are Compatible (they get along well)
• ⚠️ If they are Semi-Compatible (they might need a big tank or extra care)
• ❌ If they are Incompatible (they should not live together)

It also gives you a short reason or tip to help you understand more about their behavior.

🐟 Why Compatibility Matters?

Imagine you live with someone who always takes your food, pushes you around, or likes a different temperature than you. You wouldn’t be happy, right?

The same goes for fish. If they are not compatible, they might:

• Fight each other
• Get stressed or scared
• Get sick more often
• Die early 😢

That’s why choosing the right tank buddies is very important for healthy and happy fish.
