>Sounds like some kind of poisoning. Tell us more about >tank mates (still alive?), if you did anything special >recently, etc. Well, There used to be 4 Ramirezi. One of them I isolated a couple of days ago with completely different symptoms (Extremely fast breathing, fish sinks to the bottom). That one is still alive. In the main tank (100 L/25 gal) I kept them with 2 A. borelli and 2 undetermined specimen (A. ???) that I received a week ago. But I found a dead fish (Ram.) with spine bent about 4 weeks ago, long before the new mates arrived. Except for taking out the one Ram I didn't do anything unusual the last couple of days. In an effort to soften my water I added peat to my filter. It's the oddest thing. Martin - -*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*- Martin Rausch Dept.
