2. Nobody Has to Get Hurt

Betta can often attack other tankmates as their natural habit is to fight. By using a mirror, your fish gets to fulfill his aggressive needs without hurting any other fish in the tank.

Think of it like this. The aggressive behavior riled up inside your betta will be let out on his own reflection. Everyone in the tank, including your betta, gets to stay safe. Besides, betta will act much less hostile towards other fishes residing in the tank when his aggressive needs are met.

3. A Cure for Boredom

Betta fishes get bored too easily. A mirror can be an excellent way to spice up things for him in the tank. Let the fish play with its reflection and get a taste of fun once in a while. Betta fish usually marks the area as his territory where the mirror is placed.

He then tries to protect his territory by making sure no one enters. Patrolling is an exciting game for your betta fish. Also, reducing boredom is necessary. Boredom can often lead to depression.

6. Bonus Photographs

One little side benefit for the owner of a betta fish is better photography scopes. If you want to take your betta’s photograph with a reflection present in the tank, it’s a good idea to put a mirror. If you want flared photo of your betta, the mirror is an easy option.

How Long Before the Mirror Becomes Harmful?

Despite the advantages you are getting from a mirror with your betta fish, there are limits. Mirrors encourages stressful behavior that can harm your betta’s health. Make sure to keep the practices healthy and within limits while using a mirror.

If you want a general guideline of a precise time frame, I suggest you use the mirror for 30 seconds per day. This is if you wish to use the mirror every day. If you intend to put the mirror in front of your fish once or twice a week, you can use it for five minutes. 

However, each betta is different in its own way. So my suggestion is that you notice your betta’s behavior and monitor when he is getting too stressed or upset.

Sometimes, the fish tank can reflect your betta’s image back to him, and you won’t even realize it. Whenever you notice that your betta is flaring at nothing, it’s probably because he sees a reflection of himself. 

Your job as a betta owner is to make sure there aren’t any accidental mirrors present. Keep your betta stress-free by covering the reflective area with cardboards.

Bottom Line

Your betta craves playfulness. Other than that, flaring is a natural need for your betta fish. Mirrors play an important role in keeping your betta not only happy but also healthy. Your answer to the question ‘do betta fish like mirrors’ is, they don’t understand the function of a mirror, but the results can make them happy. That means, your betta passively likes mirrors.

You can use mirrors to encourage a healthy and natural environment for your betta but make sure you don’t overdo it. Everything is harmful when used beyond necessity.
