Tiger Macana Knifefish
One of the rare knifefish occasionally caught in Peru is the Tiger Macana Knifefish, or simply the tiger knifefish. The pattern is a tiger stripe, and the fish has a very elegant, elongated body that will grow to about 16 inches. Knifefish will eat worms, frozen foods, and small live foods and generally eat at night. Sometimes, during the day, these fish will sleep on their sides like some kind of tired farm animal, but they are very active in the evening. These fish will eat very small fish such as small neon tetras, but in general get along with most other species.

The tiger knifefish is a striking addition to my aquarium. Its tiger-striped pattern is unique and eye-catching. It’s mostly active at night, which fits well with my setup. I feed it frozen bloodworms every other day and it seems to enjoy them. It doesn’t bother other fish and just rests on the side during the day. A peaceful and beautiful species.

I’ve had this fish for three months now and it’s still very active at night. It’s not aggressive and doesn’t chase other fish. The only thing to note is that it does eat small tetras, so I’ve removed them from the tank. Otherwise, it’s a calm and elegant fish that adds a lot of visual interest.

The fish arrived healthy and looks exactly as described. Its elongated body and striped pattern are impressive. It sleeps on its side during the day and becomes very active after dark. I feed it a mix of frozen and live foods, and it eats readily. Very satisfied with the purchase.
