So i have/had a flatworm problem which i used flatworm exit for then did waterchange and ran carbon. The result...still have flatworms and killed most of my fish, i currently have a 125 gallon mixed reef with 3 green chromis, pair of perc clowns, yellow watchman goby and a small clown goby. Anyone have any suggestions on what would be some good fish to restock with, would like to get atleast 2 tangs. I had a hippo tang, yellow tang, copperbanded butterfly, redlip blenny, royal gramma all die, so i guess i am forced to restock.
