dont worry about it to much. i have a male pied that i got 26 days ago that will not eat, he will defensive strike, or grab and wrap but not eat, previous owner said he would go off feed(he also feed f/t till he stopped eating then went to live, now im try to make sure i can get him back to f/t) and a female albino who hasnt eaten in 3 weeks but has gained 4 grams. they will eat when they are hungry
