Okay, I've been wondering to myself and asked which dither I should get. I said rainbowfish, but I have 2nd thoughts. They are too pricey and will command me a hefty price for a group. My lfs sells one inch tiger barbs for .99 cents. I can easily get a group of 6 tiger barbs vs getting 6 rainbowfish which will cost me $30-$40 depending on the lfs. How are tiger barbs when it comes to dithers for africans? Do they school, will they nip fins, will they bring out my fish, etc? Thanks.
