Just like us a betta will not eat if he is feeling sick. Improper water paramaters will make him feel really terrible. And if he has nowhere to rest or hide then this will increase his stress. Bettas can go a week without food but three weeks means something drastic needs to change.
Felony theft is committed when the value of the stolen property exceeds $1000. Regardless of the value of the item, if it is a firearm or an animal taken for the purpose of animal fighting, then the theft is a Class 6 Felony.
In order for your embezzlement charge to be classified as petty theft under California Penal Code section 488, the value of the property taken must be less than $950. If you are convicted of petty theft embezzlement, you face up to six months in county jail and a maximum fine of $1,000.
