I have recently set up a community 75 gallon tank which is doing great to this point. I have been adding fish and water perameters are remaining well. My question is that I added 3 rainbow fish (thats as much as I know of their correct name) but 1 is a little larger and a different color and is always chasing and nipping at the other 2 slightly smaller rainbows. Ocassionally he will chase some of the other community fish. There is certainly enough room in the tank for all the fish and I know if it were a smaller tank it would be of more concern. My question is should I consider removing this aggressive fish as I know that it does create stress for the fish that he is consistantly chasing, which may even result in them getting sick and die, or should I just leave it alone.
The more general question is when you introduce a fish to your aquarium that is aggressive and stressful to others, what is the correct thing to do. By the way the Tropical fish store (not department store) assured me that the fish were compatible.
