In Malaysia, we call them “Ikan Laga” (Fighting Fish).
The name itself suggests violence. We imagine a fish that wants to kill everything in sight. A fish that wakes up choosing violence every single day.
But if you sit and watch a Betta in a planted tank for an hour, you will realize something surprising.
He isn’t hunting. He isn’t patrolling like a shark. He is usually inspecting a leaf. Or napping on a piece of wood. Or staring at a snail.
The truth is, Bettas are not “Angry.” They are Defensive. And understanding the difference will change how you care for them.
1. Stress vs. Aggression (The “Glass Surfing” Mistake)
Beginners often see their Betta swimming frantically back and forth against the glass and say: “Look! He is so active! He wants to fight me!”
That is not aggression. That is panic.
When a Betta paces the glass continuously (“Glass Surfing”), it means he is stressed. He sees his reflection and thinks it is an intruder that won’t leave.
- The Reality: Imagine being locked in a room with a mirror that you think is an enemy. You wouldn’t be angry; you would be terrified.
- The Fix: Dim the lights or add more plants to break his line of sight. A happy Betta is a calm Betta.
2. The “Flare” is a Warning, Not a Lifestyle
Yes, Bettas flare (puff out their gills). It is cool to watch.
But in the wild, flaring is a Last Resort. Fighting is dangerous. If a wild Betta fights, he might tear a fin or get an infection. He could die.
So, they flare to say: “Please go away. I don’t want to fight, but I will if I have to.”
If your Betta is flaring at the glass all day, he is living in a constant state of “Fight or Flight.” This burns massive amounts of energy and weakens his immune system.
3. They Can Actually Have Friends
If Bettas were mindless killers, they would attack anything that moves.
But many experienced keepers keep Bettas in Community Tanks.
- The Evidence: I have kept Bettas with Harlequin Rasboras, Kuhli Loaches, and even Snails.
- The Behavior: The Betta usually ignores them. Why? Because they aren’t colorful, they don’t have long fins, and they don’t look like other Bettas. He doesn’t see them as a threat. He just sees them as neighbors.
4. The “Puppy” Personality
Once a Betta feels safe (no reflection, plenty of hiding spots), the “Anger” disappears.
What replaces it? Curiosity.
- They investigate new plants.
- They watch you work at your desk.
- They learn tricks.
- They nap on leaves like lazy cats.
The Bottom Line
We shouldn’t call them “Fighting Fish.” We should call them “Territorial Fish.”
Your Betta loves his home. He wants to protect it. But he also wants to rest.
Stop tapping the glass to make him angry. Stop putting a mirror in front of him for 30 minutes. Let him relax. You will find that a peaceful Betta is much more interesting to watch than an angry one.
