help picking new betta

[betterfish]

I recently bought my first Bettafish and want to get a second one.
Since I was advised, that they are not good companions, I will put him in a second tank.
Could anyone suggest me an easy robust, species .And perhaps point out some differences?
They all look very nice to me.

Hey better

If you wanted another one but didn't want to set up a second aquarium you could get a female betta to go with your male if you slowly introduce the female there shouldn't be very much aggression. On the topic of betta species one of my favourites is the half-moon which I personally think look stunning.

If your tank is big enough you can put a divider in it and keep two males.
