By issues, do you mean aggression? I haven't had a problem with them picking on my other fish (except one of the young ones was stupid enough to think that he could catch a danio. Once my young zebra was staring intently at something and the barb snuck up and bit him. The danio then turned around, chased, and attacked the barb. It was actually really amusing to watch. XD). That's why none of my fish are slow or push-overs.
I really liked my tiger barbs and I fully intend to get more. I want to get a school of nine if my Rosy survives or a school of twelve if he doesn't.
Yes I meant their aggressive behaviours. As long as there is a good sized group (no less than 8, but more is better) and in sufficient space (8 on their own in a 30g is considered minimum, with larger tanks allowing other species too), they can work. The natural nippiness will hopefully be contained within the shoal and that is fine. Sedate fish or long-fin fish should never be combined in any tank with TB.
Fish behaviour is a bit uncertain. All we know is that a certain species will normally
behave this or that way, but environmental factors such as all those mentioned in the article on stress can affect fish and they may react either way. Another problem is that fish secrete pheromones, and other fish read these chemical signals. So an aggressive fish will be seen by other fish as aggressive, even if no physical contact ever takes place. This is highly stressful. When putting together a community tank (= more than one species) the normal expected behaviours of each species must always be considered and planned for, to avoid stress which can be unseen--until a fish suddenly gets diseased or dies. Stress is the root cause of almost all disease in fish, and as the article pointed out this chronic stress always shortens a fish's lifespan even if nothing else is apparent to us. To put it another way, the fish is very unhappy with its lot in life, and it wears out faster because it is constantly compensating for the stress.
