Aquarium Fish Species: Catfish

catfish speciesCatfish is considered one of the most diverse groups of fish and they can exist either as saltwater fish living near coastal areas or as freshwater tropical fish species. Unlike common fish, they do not have scales on their body, some are covered with bony plates while others have poisonous spines on their body. All of them have one common feature, which is presence of sensory barbels around the mouth region, used to seek out food and guide their way around the environment.

Catfish also do not resemble in terms of appearance on what a common fish should look like. With more than 2000 species known to date, they are most popular and widely known among fishkeepers as scavenger for leftover food in the community aquarium. Catfish can also grow very big with size ranging from a few centimeters up to more than two meters in length. They feeding behavior is usually after the aquarium lights are out and their diet varies considerably between different species. Let’s look at some of the most common freshwater catfish families.

Mochokidae (upside-down catfish) – This family of African catfish spends most their time upside-down near the surface although there are some within the family that tends to be bottom-dwellers. They are known to have attractive markings on their body and usually they grow up to moderate size from 7-35 centimeters.

Doradidae (talking catfish)

They originated from South America and their body is fully armored. The size can range between 7 to more than 75 centimeters in length and usually the smaller sized species is suited for community aquarium.

About Me

My Photo

My fascination and interest towards aquarium fish has led me to devote my time towards caring and learning about this wonderful pet.

Aquarium fish keeping is a very challenging and exciting hobby. When I first started, I never knew much or have the necessary guidance back then because none of my family members were actually a keen hobbyist. And because of that, I’ve encountered numerous failures and the worst part is having to deal with dead fish every time when you started to grow fond and getting attached to my pets. However, I persevered and took steps to find out and search for information from other hobbyist, apart from the knowledge gained and learned from my own experience and research. The blog that I’ve created here is meant to share useful information and tips about aquarium fish keeping so that new hobbyist will not make the same mistakes that I’ve made in the past."
