My 30g reef is 10 months old now, and I've had a true perc for about 8 of those months that remains very healthy. Currently there are no other fish in the tank. The tank has flatworms (the gray ones) and I need a FW killer to keep them under control since they seem to be resistant to Flatworm eXit. Unfortunately my 3rd sixline wrasse has died. They all last anywhere from 6-8 weeks before dying, and they have all died when I leave for vacation. Weird, I know, and I can't seem to explain why it happens, but that's not the topic of this thread anyway.

I love the sixline wrasse and they've always done a good job at keeping the FW's in check, but I'm reluctant to get another one since I seem to have bad luck with this fish. Is there an alternative in the wrasse family that eats flatworms and would do well in an open-top 30g mixed reef tank?
