These fish all enjoy similar habitats and can often be found in the same areas of the aquarium. Corys are also known to be good tank mates for bettas, as they are both peaceful fish that prefer to stay near the bottom of the tank.
Cory Catfish identification- how to tell if your fish is a cory catfish
The easiest way to identify a cory catfish is by its unique barbels. These long, thin appendages protrude from the fish’s head and are used to help it find food. Corys also has a very distinct pattern of black and white stripes running down their bodies.
For your convenience, I will mention a few more reasons to easily identify Cory Catfish.
1. Look at the body shape
When looking at the body shape of a cory catfish, you can tell that it is flattened from top to bottom. This gives it a very distinct appearance compared to other fish species.
2. Check out the barbels
One of the most identifying features of a cory catfish is the long, whisker-like barbels around its mouth. These help the fish to find food in murky waters.
3. Look at the fins
The fins of a cory catfish are also quite distinctive. The dorsal fin (the one on its back) is short and rounded, while the anal fin (the one on its belly) is long and narrow.
4. Observe the coloration
Cory catfish can come in a variety of colors, but they are typically some shade of brown or green. Some may also have spots or stripes of a lighter color.
5. Compare the size
Cory catfish are relatively small fish, usually only growing to be about 4 inches long.
If you see a fish that has all of these characteristics, then there is a good chance that you have spotted a cory catfish!
My final verdict
Cory catfish are a great addition to any aquarium. They are peaceful, easy to care for and make a great addition to any community tank. If you are looking for a bottom-dwelling fish that is sure to add some personality to your tank, then the cory catfish is definitely the fish for you!
Hopefully, by now you are becoming an expert in selecting cory catfish for your aquarium. But remember, even though these fish are relatively easy to care for, they still need to be given the proper attention and care in order to thrive.
So, be sure to do your research and ask your local fish store expert for advice before adding any new fish to your tank. Thanks for reading and happy fish keeping!
