Sunday, May 10, 2009 Subject: 5 year old male Oranda. For the past 12 months he has gradually stopped swimming much and just sits on the bottom till food comes. He obviously can not see well and bumps into things in his hurry to eat. I decided to trim his wen to uncover his eyes and reduce the bulk a little. Before wen trim: Research: http://thegab.org/Articles/SurgeryWen.html \http://www.koiphen.com/forums/showthread.php?t=86876 http://www.texaskoi.com/index.php?option=com_content&task=view&id=42&Itemid=58 Procedure: Laid out my tools - sterilized with Hydrogen peroxide. Towel and pan to lay the fish in. Good light. Batteries in the camera! The recipe for anesthesia is 5 drops per gallon of water (I used tank water), add more drops up to 10 if the fish does not go under after 10 min. First put it in a jar with water and shake vigorously to mix well. I used 10 drops for 2 gallons of water. Put the fish in. Red streaking immediately set in on his tail fin.
