The world of aquarium keeping is a fascinating one, with a vast array of species to choose from. Among the most popular and intriguing options are catfish, which have captured the hearts of many aquarists. But have you ever wondered just how big these fascinating creatures can get? In this comprehensive guide, we’ll delve into the world of aquarium catfish, exploring the various species, their habits, and most importantly, their size.
Aquarium catfish are a diverse group, with over 2,000 species spread across the globe. From the tiny Corydoras catfish to the massive Panaque catfish, each species has its unique characteristics, habits, and requirements. Despite their differences, all catfish share one common trait: their ability to thrive in a well-maintained aquarium. But before we dive into the world of catfish, let’s take a closer look at why size matters.
Why Size Matters
When it comes to aquarium keeping, size is a crucial factor to consider.
