Would tiger barbs be alright in my 55 gal.? The info is in my sig. I may getting rid of the last BR parrot, I already sold one back today.

He wasn't thriving in my tank, he was too shy. So, for his own good I sold him.
So, would tiger barbs be alright (6+) & possibly 2 pictus?
What else would fit? I was looking at black/white skirt tetras.
Of course, this is a long ways down the road, after the
ICH is gone.
Just bounce off some ideas on me, I'm going to be doing a lot of research in the nect month.
Also, if you have any ideas for a 20 gal. I'm torn between a mating pair of convicts or a community.
Thanks!!
