Senegalese Bichir
Also known as a ‘Dinosaur Eel,’ it can add an adventure to your aquarium. These fish look like prehistoric dragons with a slight variance in size and color pattern.
They generally live a long time and get along with any fish that cannot fit into their mouth. They make an excellent addition to a large fish tank – well, with the exception of tanks with those small fish. They are easy to care for and feed.
Senegal bichirs and albino Senegal bichirs are captive bred and sold at a small size – usually about three inches. At this size, they are suitable with just about every aquarium fish though they may grow up and eat the smallest neighbors in a year or so, so plan accordingly.

I bought a Senegalese Bichir for my 55-gallon tank. It’s been two years and still active. It doesn’t eat my larger fish, but I’ve had to remove a few tiny shrimp that were too small. The fish looks unique and adds a cool presence to the tank.

The bichir arrived healthy and was about 3 inches. It’s calm most of the time and only eats small prey. I’ve kept it with larger corydoras and it’s coexisting well so far.

This fish is a standout in my aquarium. It has a prehistoric look that’s hard to ignore. I didn’t expect it to grow much, but it’s now 4 inches and still active. I’m happy with the purchase.
