4 damsels in a 20G

I saw the blue velvet picking on the toadstool twice this morning and the four stripes actually pulled one of the flags off the rack. That's the last straw, I made a divider from an old screen door and subdived my tank into 3 sections and move the rock. I caught them:D . They seem to be taking the trasition well, no chasing. I also moved 2 more rocks from the display. hopefully they stay this way.

1 week in the 20g and they are still fine. I am thinking of getting a 29g or even a 40g if it will fit on the ledge, I feel bad for them not having long enough tank to swim.
