Cool, sounds like we haver the same community tank!
Here is whats in my 75 gallon(4 ft long):
13 tiger barbs
1 RTBS(died a couple days ago, eaten by my cat
)
4 pearl gouramis
2 red claw crabs
2 bamboo shrimps
2 clams
I have a heavlly planted tank, and they dont eat my plants, at all. I got nips from time to time(pearls) but they dont do it now.
Its easy to find mates for tiger barbs, actually, and they dont get scared when my lights are on. Any semi aggresive fish, thats not to finny(e.g. gouramis, other barbs, danios, cichlid-as dither fish- , other fast moving fish that wont get bullied around, althought if you have more tiger barbs, there is less chance of nipping.
I did have a pictus cat in there, But I moved it in my 100 gallon, and they did just find.
here is a pic, btw. This was taken 2 months ago(the tank was just recently taken down, and repalnted). I now have 10 more kinds of plants added, mostly red leafs. Ive also since rearrange the plants.
But this shows that my tiger barbs are doing just well even with bright light.
