each animal is an individual, no one morph is pickier, nastier, meaneier, nicer, *insert other adjective here*, ect. so don't believe anything anyone has told you otherwise.

as far as odd traits, spiders got the apparent neurological issue, some say womas do also. caramel albinos tend to have kinking problems, super black pastel/cinny can duck bill, some BEL can bug eye.

but as far as personality and how they act, that changes animal to animal, nothing to do with what morph they are.
