Need advice, presently I've got a sail fin, a purple and a fox face to be added to a new tank set up. I want to add an Achilles, Blue throat trigger and a Unicorn. Should I put them in QT tank together before the transfer, should I add them separately or group them in any special way. Chime in and let me know what would give me the greatest chance for success. I'm thinking that if I QT the unknown Achilles with my two tangs and fox face that don't have ick I might be risking their health
