Are King Betta Aggressive

Mostly bettas are aggressive that’s why they are called Siamese Fighting fish. King bettas are extremely aggressive and also they are solitary fishes which means they want the whole tank to itself. They don’t like to share their tank space. And if they do share, they become highly territorial.

They got their name King Betta from this trait of them that they like to rule their tank. When it comes to territory, male king betta fish are extremely territorial. They will literally attack any fish that comes into their territory. Trust me when I say they are territorial because they won’t even tolerate a female king betta fish in their territory until and unless they are mating.

Best tank mates for King Betta Fish

As I said earlier king betta fish are extremely aggressive so you have to be very careful while choosing their tank mates. 

Well, I do suggest my reader keep male king betta fish alone since they don’t like to share a tank, but only king betta fish in a tank will make the tank dull. So if you want to add any fish with king bettas then add normal-looking, docile fish in the tank as they won’t attack a submissive fish.

King betta fish will only attack bright-colored and long fins fish so while choosing tank mates for them, choose a docile fish which are also bottom dwellers like Corydoras catfish, Khuli loaches, guppies, and ghost shrimp.

Most importantly, don’t put male and female bettas in the same tank, until and unless you want them to breed.

Tank size of King betta fish

Some people think that king betta fish can also survive in tiny fish bowls because of their small size but that’s not true. They need a proper tank of their own. King betta fish requires at least a 5-gallon tank to survive. 

This is because king betta fish are active swimmers so they need lots of space to swim freely and happily in their tank.

Another important thing is to install a water filter system to remove waste material from the tank. 

Decorations in the tank

It’s nice to decorate your tank with plants to imitate the natural habitat of king betta fish. Floating plants are a great addition to the tank. In these plants, fish will create bubble nests for the process of mating. So it’s always a good choice to add some safe floating plants to the tank of king betta fish.
