Did you have a lot of flow? Possibly to much for a young atf? Or maybe you had no rest spots?
Yup. Extremely annoyed. Aimara I understand because I screwed up. No idea what happened with this guy.Ouch :/ feel sorry for you mate losing two fish in that short time must suck.
Did the fish look really skinny? Could be something internal, parasitic possibly, which could also explain why it wasn't eating. Wes treats his fish AFAIK, has always been good quality ime, but it is possible he something stuck through it as such a case isn't unheard of. Your turn over doesn't sound bad, nothing like the sticky suggests which I would deem as to much for a young fish.
