betta fish tail biting

All this fish ever does is attack his own tail. He is extremely overly-aggressive and destroys his tail fin whenever it gets long enough for him to reach it. I vary his diet with bloodworms, live mosquito larvae and betta pellets. He eats like a pig, and then goes back to spinning in circles trying to reach his tail again! SOOOOOOO frustrating... maybe I'll just get a new fish :(

I had the same problem with my Betta Fish I put 2 guppies in his tank and he chased them and stopped biting his tail. I guess he was to preoccupied with chasing them that he forgot about his tail.

If your betta is biting his tail it means he's stressed

Everywhere I've looked has different reasons for why a betta might bites its own tail. Some places says it's unknown, but apparently it's common.

I need help! I got my better fish couple weeks ago and he has been doing fine. I put water conditioner, filter, heater, plants and he lives with very small tetras (five) and a sucker fish. He has been doing fine but I found from one day to another his tail was ripped and had this almost cloud looking thing around it. I don't know why this is happening because his tank is clean and he gets along fine with the fish and eats well. I saw him his fins getting stuck in the filet and it got worse so i tightens a pantyhose over it so his tail wouldn't get worse. Please help because I am worried for my poor little baby and don't know if he is ripping it off himself, or if it was the filter or fin rot. Sorry for the long text but I don't want him to suffer and need to know!

Yes, my tetras nipped my betta's tail. Grrrrr

The cloud looking thing is possibly ich. Please research on it. Also, tetras are known to be fin nippers. And a ripped fin is open to bacteria and parasites.

I have a halfmoon betta with huge fins. I've heard fin biting can be because of stress, but my betta shows no signs of stress. He's always energetic, exited, and does a little greeting when I go over to the tank. He nips his fins a but to be more quick and agile. Is this normal?
Mark Brown
Mark Brown - 5 years ago
Mine greets me too. He will be hanging out on one of his leaves, not really doing anything and when I come over, he comes to the glass, faces me and wiggles his fins. It is so cute.

the betta fish is hungry, just give him a lot of food
Zachary - 5 years ago
Betta fish are always hungry and will bave an appetite depsite being full. This is a sign of aggression, not hunger.

Also a bit late, but here is my suggestion:
As some people before me have already mentioned, he could be stressed out. Not necessarily because he is bored, but because his tank is too scarcely planted. Bettas like dark, heavily planted tanks which resemble their natural habitat.
Tank size might have been a tad bit too small for him too.
AnnPeek - 8 years ago
I think they do this when they are stressed, or the water conditions aren't quite right.
Bobzeda - 8 years ago
I think some betta are just crazy.  I have four.  They all have the same tank size and similar decor.  Only ONE constantly bites his tail.  He also has the prettiest tail.

I know right. It's ridiculous. When I got him, he was a feathery tail, now it's all covered in shreds. I was thinking it could have been the filter since I never caught him tail biting, so I added more water to decrease the pressure of the water flow and covered parts of the filter tube.

Hey so this is a couple years late but this looks like he is bored.  I've been trying to extend my research on tail biting (thankfully have never dealt with it personally) and I realize that a lot of times fish are not given a lot of mental stimulation or even physical stimulation (as in new additions to the tank, something to chase, etc).  I would imagine by now you no longer have your betta but thank you for sharing this video! 

Also what size was your tank and did you have a heater?

Sometimes varying the tank by adding hides (terracotta pots, the small ones, work great), floating objects that are safe (plastic balls, for example), colored marbles, etc. help.

dont b frustrated coz its hereditary. during the mating season. no matter the unstable enviroment or the water quality or the food. they turn emotional & fussy easily. try to give him a female or ye, slap the table slighty to distract him whenever he try to do it. this behavior may change.
TwistedNerds - 9 years ago
I have the same fish! black head blue body but the tail does not have that color spot change

Try adding some live tank plants and make sure that the lighting in his space is set up so he doesn't see his reflection in the glass. I have betta and cichlids, both get hyper aggressive when for ex. the tank light is on but the room is dark.

This is what my Betta was doing, but soon I'm moving him to a three gallon tank. And the same as my other fish. I hope it's going to work cuz I like Really really like my halfmoon and my veil-tale alot. The tank they are in now is a one gallon. :D!
TheHaloChief117 - 10 years ago
maybe he likes the way his tail tastes
109367 - 10 years ago
My friend had one like that and every time he went to bite she hit the table his tank was on really hard and scared the crap out of him. It's like training/correcting any other animal, he associates biting his tail with something unpleasant and he eventually stopped. Whether that's the best way to stop it or not I'm really not sure lol

Just realized today that my Betta is a tail biter. I've been told that Stress Coat can help. I'm also going to move mine to a bigger tank and get him a tank mate.

The reason many bettas nip their own fins is because sometimes they feel like their tail are to heavy and rather go lightweight by taking some fin of' although it can be dangerous leading to fin rott in my case.
coolfreak2000 - 12 years ago
the fin nipping is a common trait in the halfmoon betta but thats a veiltale so i have no idea why lol
Luimeril - 12 years ago
@BigolePappy2 no one knows. i guess it's like a human biting their nails when nervous. x:
Luimeril - 12 years ago
tail biting is common in bettas anymore. to stop it, is pretty easy sometimes. he's either stressed by something, or bored. best way i found to figure it out, is to give him more plants to hide in and re-arrange his tank decor often. if he still does it, he's stressed by something, usually the filter current. it's NO reason to get rid of a betta, though.
withramya - 12 years ago
Mine is a tail-biter too turns out! The tail starts to grow and then he bites it off. I have never seen him do that actually. He is alone in a 15 gallon tank (maybe I should get him some tank mates). He is a veil-tail and it is so uncommon for VT to be tail biters.! (frustrating)
Roland - 13 years ago
my betta's tail would start to grow back then 'CHOMP* - back to square 1 again. i've given up worrying about it now. used to treat his tail with bettafix/tri-sulfa etc and tried just about everything to stop it but i've given up now. if that dumb fish wants to ruin his tail then fuck it - whatever.

I thought my betta Blu had fin rot but I just caught him chasing his tail today...yeah I tried to distract him but I know he's done this before....He sort of resembles your betta.
