Uhhh, yeah, I would say that something is not right with it. Not sure if its a hernia or what, or if it will be fatal. Just keep a very close eye on it. Perhaps add some Melafix to help fight any type of possible infection.
I had the same thing with one of my angels. I do believe that overfeeding is the culprit of this though. I didn't feed it for a day or two and it cleared right up. It is still happy and strong 8 months down the line.
Thanks, i poster this on the ER forum and got a lot of good advice there. My angel is looking MUCH better today and all has cleared up. Good to hear your angel made it. A guy at my LFS also had it happen apparently and his angel is ok seems to be something angels get?!?
