i recently purchased a Dejardini Sailfin from a LFS. He was traded in by someone who was taking down their tank. He is showing some signs of HLLE now, adn I'm curious if somethign may have triggered it, or it was there to begin with and is just now showing up. My Mimic tang is acting weird, and is showing signs of ich. There is no catching them, to get them out of the tank and QT, so I'm treating with heavy garlic and Selcon feedings, every other day. Anything else I can do to help them out? Also, can HLLE spread from fish to fish? Thanks.
