What to consider when choosing fish for your aquarium?

Setting up an aquarium is both exciting and a bit overwhelming with so many fish options out there. I recently found myself caught between choosing colorful community fish or unique, solitary varieties for my new tank. Each type has its own appeal and care requirements, which adds a layer of complexity to the decision.

I’ve been leaning toward species that thrive in enriched environments since my roommates and I really care about animal well-being and stimulation. However, some fish have specific needs regarding water conditions or compatible tank mates, which makes things trickier. What factors do you think are most important when selecting fish? Do you have any favorites that you would recommend for beginners looking to enhance their aquarium with enrichment activities?
