I've only ever seen one of mine bite and that was the one who only bit his fins after he got sick with a mystery illness that I ended up not being able to cure. He was a rosetail, and up until that point never touched his fins.

Pinkerton might have bit due to his coloring, he was a pale pink butterfly DT, and from what I hear fish with his coloring seem to bite more then others and some suspect there's a genetic component to it. He'd stop for a week or so then start up again.

Bruiser, royal blue VT, only started biting after he ripped his caudal and dorsal fins off on the filter intake tube. He let the dorsal grow back but insisted on biting back the caudal ever time it got around half grown back. I almost suspect that he liked it that length. For reasons that I can't figure out, after months of his trimming it he stopped and has left it alone for around 6 months now.

Cinnabar was a red VT and never touched his fins. Lagniappe is a yellow VT and leaves his fins alone. Picasso is a marble rosetail / double tail and he's never bitten his fins. Cork is a blue, red, bicolor HM double tail and he leaves his fins alone. They are all in heavily planted tanks, but the tanks vary in size from 2.5 gal to 20 gal, they are all fed the same diet.

I sometimes think it's luck of the draw whether or not they bite. It does seem that the longer the fins the more chance that they might but that's probably because of ease of access to the fins.

Good question and apologies for belated response.

That comment was based on observing fish in the wild since 1988 with my first scuba certification.

Now since we're underwater for typically an hour at a time, there's no way to say for sure that wild fish aren't fin biting - I've just never observed that behavior in 500+ hours.

Since so many aquarium fish are wild caught, does fin biting happen in other populations?

I've always said the sea was my aquarium so I'm a novice when it comes to captive fish

I wonder if it could be analogous to a bad habit like cuticle biting in humans?

It just seems like a bad idea from an evolutionary perspective, a fish preoccupied with fin biting would make an easy target.

So it's fair to say there's a genetic component?

Again, from an evolutionary perspective I'd think that behavior would be weeded out in wild fishes.

The long and the short of it is no one has conducted an actual study that established a concrete reason why Betta sometimes fin bite. The only "evidence" is the anecdotal.

As far as the gentic/color-relation, Thai breeders noticed it seemed a higher percentage of white Bettas were prone to biting. So they tried breeding the trait out. No success. This comes from a person who used to import his father's Betta on eBay.

One also seldom sees a Betta fin bite. I never have.

And some people seem to have a higher percentage of biters than others. I have had, maybe, 10. All things being equal, three or four bit until I moved them into a 2.5; at least five bit in transit but stopped completely so I don't really count them. The only chronic biters I've had were white or marbles.

The above is out of hundreds of Betta in 52 years. Two were HMPK. The rest were HM. None, as far as I know, were related.

All were in very heavily-planted tanks @78F with same lights and light schedule. Black substrate with large areas of shade.

BTW, I am not arguing; just trying to make the point that there are so many theories and scenarios. One (or even five) is impossible to say is definitely a factor.

I see what you're saying.

We definitely need double blinded repeatable clinical studies

cause anecdotal observations are just....well anecdotal

But you've been observing Betta for 52 years?! That's more than Guru status that's Legend

What I find interesting is those who bit in transit never did again.

Breeders/Sellers often do daily flare sessions. These are Betta kept in bare tanks of one gallon or so. From what I've been told, percentage-wise fin biting is low. This seems to offer support to LBF's frustration theory.

See? So many possibilities.

BTW, 52 years makes me no guru. 😉 I learn something new almost every day
