How do you pick the best fish for your aquarium?

Choosing the right fish for your aquarium can be quite challenging, especially with so many species available. I’ve been experimenting with different types of fish lately, and just when I think I have a good handle on things, I discover another fish that looks just as interesting.

I’ve found that the temperament and size of the fish play a significant role in maintaining harmony in the tank. If you’re aiming for a peaceful environment, it’s essential to select species that can get along well. Have you ever faced unexpected compatibility issues in your tank? What tips do you have for selecting and introducing new fish? I’d love to hear your experiences!
