Are tiger barb fish really aggressive fish?

Answers:
Tiger barbs fall under the category of semi-aggressive tropical fish. Yes, they can be aggressive, but they don't necessarily have to be. There are a few things you can do to help them get along with other fish in your community tank.
*Buy a group of three (I noticed someone suggested six, but I'd only recommend that for a tank that is 75 gallons or more)
*Be sure to only get them if your tank is large enough. I suggest at least a 55 gallon tank.
* Do not put them in a tank with a lot of fish smaller than they are. (They may leave them alone; they may not--why take the chance?)
*Rearrange the ornaments and plants in your tank about once a week. This will keep them from getting territorial.
* Make sure you are feeding them properly. You can find many feeding guides online.
*Make sure your tank is not overcrowded--the old rule is one inch of fish per gallon of water, BUT larger fish need more room (that would be like saying a 10 inch cichlid only needs a 10 gallon tank which is clearly grossly inadequate!) An overcrowded tank causes even fish that are not usually aggressive to lash out due to the extreme stress it causes.
Hope this helps!

Yes.
Thanks for the 2 points!

---

Yes they are including the Albino varieties. They have a tendancy to nip at the fins of other fish.

---

Only if they're kept in smaller group then 6
If you kepp them in a group of that least 6, it will cut down the aggressive behavior towards other fish dramatically

Hope that helps
Good luck

keep them in threes or more they are fin nippers

These fish are definitely fin nippers. If kept in schools they tend to leave the other fish alone

I have five tiger barbs and in my case they dont tend to bother the other fish species much. However they often poke and fight their own species.
I'm not sure how they are with other people as i'm sure each tiger barb may be different.
