Gouriami And Tiger Barbs

[SophieLT]

hi

i have had the tank running for a year and still learning.
I have 6 tiger barbs,2 guppies(both male), 2 gouriamis, a lace gouriami, a plec, a RTB shark, 3 clown loachs, 3 tetras, 2 swordtails(1 pregnant female and other male) and a lot of baby swordtails(unknown sex)
3-4 Harliquens and a dalmation molly.

My tiger barbs have lots of fun because my RTB shark chases them about but they don't stress and they don't nibble at any tails. But they do mouth fight, just like my Kissing gouriamis.

Is this normal?

Thanks.
