Looking for some info on as oscar not eating, do they do this by choice? I have had him for 9 monthsand is approx 8-9 in long. Things have been going well, but for no reason he has stopped eating. Levels are all good. don't know of any new stress not much has changed. Only thing I can see is he breathes a little funny, I can see his tongue sometimes poking out and opens his mouth a lot.
