Does anyone know if there is a reliable difference in levels of aggression among the different types of bettas? As in, are crowntails more/less aggressive than halfmoons, etc? For some reason I thought I had read that crowntails are less aggressive than other bettas, but I have no idea if there was any substance to this claim. Is there any link at all between these 2 traits?
I'm going to be keeping a male with my corys which I don't think should be too much of a problem, but I just want to know if there's any way to choose a less aggressive betta. Thanks & hopefully this isn't too silly of a question!
 
All those strains are Betta splendens. Bettas have varying personalities so it is expected that some can be aggressive, some are docile especially for males.
 
I've got 4 VTS, 3 CTS and one HM betta.

They definitely vary in their levels of aggression.

My most aggressive betta by far is a CT. But the other two are mellow boys.
But man, is he ever noticeably aggressive compared to all the others.
 
lupin hit the nail on the head again. lupin RAWKS. and id try fancy female bettas. more of a good thing there.

my veil tail was going to get a few guppy friends-nope and a few ghost shrimp-nope lol.
hes a beast.
 
Actually there are a lot more types of bettas than just splendens in all their various fin types and colors.

For example, Betta imbellis is a fairly peaceful betta which can be kept in mixed sex groups in the same tank.

There are a whole lot of bettas besides splendens.
 
With betta splendens, the level of aggressive depends upon the betta itself and it's breeding. Finnage and colouring have nothing to do with it.
I've seen Pineapple bettas where the males have been real lazy, un-active fish, that don't flare at all. Then I've seen Opaque and Royal Blue males that don't stay still at all and will flare at people who walk past them. Then I've seen the same thing, cept the other way around, with the Pineapple bettas being more active and highly aggressive and the Opaque and Royal Blues taking no notice of things happening around them.
It really all depends heavily on breeding. I've had Opaques that have been real passive and yet intelligent, who have always taunted the other more aggressive bettas. None of my Opaques have been aggressive, just smart and annoying. All my Opaques have come from the same line.
My brother has had a single Crowntail, it only flared at the Opaque bettas and would hide if a betta of another colour was brought to him, be it male or female.
Then I've had highly aggressive females that have been blue/red crosses. I had a single female that wasn't aggressive, she was a little purple crowntail and very timid.
I will admit though, I find Royal Blues, Steal Blues, Greens and Dark Red bettas to nearly always be the most aggressive. Opaques have always just been plain intelligent little buggers and Crowntails, just rather interesting little fish that I enjoyed having due to the low aggression.

It all comes down to breeding, I've only every had highly aggressive Blues, Reds and Greens, some Marble Bettas have been a bit nasty, but not as bad as the first.
That is just my opinion anyways.

:iagree:

I also think genetics play a big role.....
 
Thanks for the input guys.. I was just wondering because I'm going to be getting a betta (splendens) to put in with my corys. I definitely like the idea of getting a few females, but I haven't seen too many fancy ones in my area.
