I want to know what sort of tortoise/turtle i own. its really tiny. a friend of mine says these will grow pretty fast. they don't seem to eat their turtle food they gave at the pet store. i've been asked to try raw fish. is that a good idea? and now it is developing a white stuff near its eye, which it doesn't seem to open. what should i do with that? i have no idea how to look after a turtle. and i have two. help. again, they are really really tiny and i'm scared they're going to die.
