I keep a small group of alterna and have a male w/ a strange problem I've never seen before. I keep a fairly large group of NA milks, and have never seen this before in them either.
He has this concave that starts just behind his head on about 5 or 6 inches of his ventral. He looks kind of desiccated in the photos but I assure you he isn't. He is still very active and was last fed November 9th. He didn't have the con-caved ventral at that last feeding. He isn't wheezing or sneezing, but I did open his mouth to see if I could see anything unusual, and only found a slightly tacky saliva, but not alarming.
Have any of your seen this before? And any suggestions or ideas would be appreciated.



Here he is as a robust adult before the con-caving. -Dell
