One of the most popular fishes to keep as pets in a home fish tank are Cory Catfish.
They are effortless to maintain; hence, even a newbie at aquariums can easily keep them without prior experience.
However, before deciding to get one, let’s get to know a little more about them so that it’s easier for you to keep them.
Like all other family members of the catfish clan, Cory Catfish are also bottom feeders.
It means that they like to scout at the bottom of the tank and search for leftover food in the gravel rather than eating the meal directly at the top of the tank.
The best thing about Cory Catfish is that they are peace lovers. They are never involved in fights with other fish.
They also tend to find their food on their own without causing any trouble to other fish in the tank.
As bottom feeders, Cory Catfish are highly beneficial to a fish tank.
They remain civil with other species of fish, and their bottom-feeding habit and searching for food at the bottom of the fish tank make them the perfect vacuum cleaner of the fish tank.
Yes, Cory Catfish are Bottom Feeders
Cory Catfish like to dwell at the bottom.
So, most likely, you will always find them at the bottom of the tanks searching for their food and not with other fish in the tank or swimming along with them in the middle or surface of the aquarium.
They like to stick to the bottom and find their food. This habit of the Cory Catfish makes them very attractive and appealing to aquarists.
They have become known in the fish world for being peaceful and calm.
They are the least bothered and always mind their own business at the bottom of the aquarium, while finding their food in the gravel and sand.
Cory Catfish have around 165 different recorded species, and each is different from the other.
The only similar and desirable characteristic among all Cory Catfish is that they are all bottom feeders.
Another essential feature of the Cory Catfish is how they look. Their appearance is quite distinguished from other fish. They have armor-like skin.
The overarching genus name for this group of fish is Corydoras which comes from two Greek words (Kory and doras), which mean helmet skin.
This name is because of the unique bony plate that runs along the length of their body, giving it an armor-like shape and look to them.
Considering the name and body shape, their calm and peaceful behavior is pretty contradictory.
The different species of Cory Catfish are different in size too and range from 1 and 4 inches in length.
Bottom Feeder Fish are Good for Your Aquarium
Bottom feeders are helpful to the aquarium’s aquatic life.
Cory Catfish are like your personal underwater recycling machine. They eat all the leftover food and suck all organic matter that would otherwise rot and make your fish tank dirty.
It wouldn’t be wrong to say that a Cory Catfish is like hiring a personal cleaner for your aquarium.
They prevent your aquarium from getting dirty and looking dirty; Besides this, they are also good-looking.
The regular colorful, attractive and bright fish that you generally take from fish stores are either surface or mid-level feeders. This can lead to disputes over territory between the new and old fish.
Most fish keep lingering around the surface or in the middle of the tank, where they all like to eat and feed themselves.
Moreover, when you bring too many surface feeders, they keep hovering around on the surface, leaving your aquarium looking empty in the middle and bottom.
When you bring in new fish and take the different types of feeders, you will be able to create an aquarium that is peaceful, balanced, and full of life.
So, it would be best if you always remembered bottom feeders when getting fish for your aquarium because they are great for the water environment.
They complete the look of a lively aquarium.
