demonclownfish - raccoons are like threadfins and are quite destructive in reef tanks. especially towards small anemones. bubbletips included. as well as aiptasia
i saw a soft coral dominated TOTM once with a threadfin in it though. seems doable, but again, depending on your choice of corals. in a tank full of meaty LPS, i don't think it's a good idea.
SDguy - how may i address you btw? and you manage to get one of them to eat pellets and flakes? that's impressive!
