Tiger babrs no tails

[Galvin88]

Hi guys
Just noticed 3 of my bards, a tiger and 2 green barb have the ends of there tails missing.
Not sure if it's rotted off or been bitten off.
All the other fish including the rest of the bards are fine , just the 2 have no tails
Anyone have any idea if it could be fin Rot or bitten off
The other fish in the tank apart from the barbs are
3 oddessa barbs
1 red tail black shark (only 3 months old)
3 botia Dario loaches
2 dwarf gourami

how many tigers do you have?

they are notorious for fin nipping and fighting.

it does look like it is growing back and they do grow fairly quick.

just to rule out water quality, what size tank is it do you have any test results

I have 11 barbs, didn't known they would grow back so Im happy about that tbh.

My tank is 63 gallons I did a big water change yesterday, so don't have any test result. Last time I did a test was last week and got
0ppm ammonia
0ppm nitrite
Between 5ppm to 10ppm nitrate
