Well... The question here is the probable size of the Rosy Barb. When I wrote our profile and researched several reliable sources, I came up with the normal being 3 inches though some suggest 6 inches possible. 1077 mentions 6 inches, and I assume he has had the fish at that length. I have not kept this species myself. I just checked with my biologist friend Matt Ford's data on Seriously Fish and he says aquarium fish normally reach 2.5 to 3 inches, with some reports of 4 inches max.
If 3 inches is it, then 8 RB and the others are fine. But if this fish does reach 6 inches, that's a very different situation, and I would stay with six. I sat in front of my 90g which is also 4 feet in length and tried to imagine my group of five male Congo Tetra which are close to 3 inches as if they were 6, plus the added girth, and I would find the tank rather full.
