I also think it's a bacterial infection. Whatever it was, that looked really bad and i don't think you could've done anything to save it. Sorry for your loss

You are very right it is really hard to get a definite id on these guys. Unfortunately there is no way of telling which river they came from so i guess it'll just be L015 from now on, thanks for that

Asked many people, some say L015 while others say its L202. Can anyone who has owned or owns any of those two L's confirm which L number it really is. Thanks
