When you look at a Goldfish, it looks through you. Its eyes are blank. It is just swimming and existing.
But when you look at a Channa (Snakehead), it looks at you.
This is the main reason why people get addicted to keeping them. Yes, they have beautiful flowers and colors. But the real hook is their personality. They don’t act like fish; they act like dogs.
Here are my notes on the surprising intelligence of these “monsters.”
1. The Moving Eyes
The first thing you notice is the eyes. Most fish have eyes fixed on the sides of their head. They see movement, but they don’t really focus. Channa are predators. Their eyes can rotate. They can look up, down, and forward.
If you walk past a Channa tank, the fish doesn’t just swim away. It will often hover in place, turning its eyes to track your movement across the room. It feels like you are being watched by a cat, not a fish.
2. The “TV Watcher” (A Friend’s Story)
I used to think people were exaggerating about how smart these fish are. Then, a friend of mine who keeps a large Channa Marulioides (Maru) told me a story that sounds crazy.
He swears that his fish watches television. His tank is in the living room, next to the sofa. He told me that in the evenings, when the TV is on, the fish will settle into the corner of the tank nearest the screen and just float there, staring at the flashing lights for hours.
If he turns the TV off, the fish swims away. I don’t know if the fish understands the plot of the movie, but it is certainly curious about the world outside the glass.
3. Recognizing the Owner
This is something scientific studies have actually supported: Fish can recognize human faces.
My friend demonstrated this to me. When I walked up to the tank, the Channa was shy. It retreated to the back, hiding under the driftwood. It didn’t know me. I was a “stranger danger.”
But when my friend walked up, the behavior changed instantly. The fish swam right to the front glass, “wagging” its body and fins like a happy puppy. It knew that this specific human brings the food.
4. Interactive Feeding
You don’t just dump food in a Channa tank. You interact.
- The Follow: You can put your finger on the glass and drag it left and right. A healthy Channa will follow your finger perfectly, ready to strike.
- The Jump: In the wild, Channa jump out of the water to catch insects on hanging leaves. In the tank, some owners train their fish to jump slightly out of the water to snatch a cricket from tweezers. (Note: Be very careful with this, or they might jump onto the floor!)
We call them “Monsters” because they are fierce predators. But I think we should call them “Water Puppies.” If you want a pretty decoration, buy a Tetra. But if you want a pet that interacts with you, recognizes you, and maybe even watches a movie with you—get a Channa.
