Scientific Name. Synodontis nigriventris.


       
Comments
All Synodontis Catfish are very good aquarium fish. They get along with other fish, and they're energetic, healthy, and interesting to watch. Many of them swim upside down, when they are excited or hungry. The Upside Down Catfish, Synodontis nigriventris, swim upside down most of the time.
 
There are many species of Synodontis catfish and all of them are usually nocturnal, so they need a cave or a piece of drift wood to live under during the day.

Be sure the rocks or pieces of pipe and everything else you put in your aquarium will not contaminate the water. Click here to read about how to avoid contaminating your aquarium.

 
 
Picture of an Upside Down Catfish for sale at Aquariumfish.net, tropical fish stores, where buying fish is easy.   Here are some Upside Down Catfish like the Upside Down Catfish for sale in our facility. Click here for more details about buying Upside Down Catfish and other wild fish from us.
 
 
The Upside Down Catfish, shown above, are hiding upside down under a rock. They frequently come out and swim around the aquarium upside down. Upside Down Cats are hardy and energetic, rarely bother other fish, and are rarely bothered by other fish. They often live for many years. 
 
 

Appropriate home
An aquarium with at least 29 gallons of water, an exterior power filter with a BIO-Wheel, a maximum of 1/4 inch of gravel, and an aquarium heater adjusted to keep the  temperature of the water between 78 and 82 degrees F. Click here for more about warm water aquariums.

 
Cichlid Stones - Ceramic Aquarium Caves - Click on this image to buy Cichlid Stones.
 
Synodontis Catfish enjoy Cichlid Stones, which are hollow ceramic aquarium caves that make ideal homes for Synodontis. Many Cichlids, Loaches, Eels, and Sharks also love these caves. Click here for more about Cichlid Stones.
 
 

Recommended Diet
Floating Flake Food for Tropical Fish. Click here for more about feeding fish. I feed these catfish a few live Black Worms every other day. Click here for more about Black Worms.

 
 

Compatibility
Upside Down Catfish enjoy being together, so it's best to keep a group of at least three of them together in the same aquarium. Elephant Noses, Baby Whales, African Black Knife Fish, and other Synodontis Catfish are good tank mates. U.D. Cats are also kept in aquariums with Clown Loaches, large Gouramis, Tinfoil Barbs, Giant Danios, and a Plecostomus Catfish. Click here to read more about several other groups of compatible fish.

     

Size and Life Span
Upside Down Catfish can grow to 4" and sometimes larger. They live for 10 years sometimes longer. A friend of ours, Mr. Frank Dayes, got some of the first Synodontis Catfish imported into the United States in the early 1950s and kept them for over 25 years.

 
 

Customer Comments

 
Hello, I was wondering if you could answer a question for me about the upside down catfish. We have had ours for almost 14 years, can you tell me how long or how old the oldest upside catfish in captivity is or how long we can expect ours to live. I know for us it won't be a pleasant experience when it does die, but was wondering how long we might have left?
 
Thank you for your help,
Mrs. Lee Ann L.
 
 
 
Reply. Hello Lee Ann. Thank you for reporting about your Upside Down Catfish (UDC). You've had it for 14 years, so it's older than than that. It was probably at least one year old, when you got it. That is just an estimate. If so, your UDC is now over 15 years old.

As mentioned above, Mr. Frank Dayes, told me he kept some types of Synodontis Catfish for over 25 years, and I saw those Synodontis, but I was never sure what species they were. Your UDC is a Synodontis nigriventris. I think it may live for several more years and maybe for many more years.

Good luck with your fish.
