A potential problem with this ^^^ is that they may not be running the copper at therapeutic level and or long enough. We've seen lots of fish come out of systems like this showing no signs of ich/velvet and then the ich/velvet comes roaring back without the usual visual symptoms. Not cool. Keep an eye on the Starry Blenny and the Goby. Last time I put two together in a QT, the SB went caveman on the Goby. Ended up putting up eggcrate between them to keep the Goby alive. Today they are in the DT and get along fine. Crazy fish. I fed the SB and Goby my usual smoothie: Take several different frozen fish cubes: seaweed, mysis, clams, etc. Place in a tupperware in the fridge and allow them to "slump" (thaw). Mix together. Drain/strain off excess water. Add a few drops of Selcon, Zoecon, etc. The mix will stay good in the fridge for a few days. The fish love it.My LFS runs copper in their fish tanks already,
