Yeah, there are tiger and also rosy barbs in there. Their shoaling behaviors are different and they lend both motion and color to the tank. Rosys swim back and forth (up high usually), and the tigers sort of "ball up" and tumble. I really haven't had any problems either way with the barbs. Closest thing to a problem was when I put the larger ebjd into the 75g tank. The barbs were following him around nipping at his tail (I guess it looked different than everyone else's). He put up with it for about a minute and then wheeled around and snapped at them a couple times and they never did it again. I have three tanks, a 20g tall, a 40g, and the 75g. I have tiger barbs in all of them with the cichlids and really haven't had any problems at all - so far!
