in my perpetual intellectual quest for greater authenticity and a closer walk with nature, i am always thinking about what i can do to make my fish tank and turtle tank closer to being a slice of nature- real, region-appropriate plants, decor, etc. in that light, what- if any- creatures would make suitable tank mates for an turtle such as scooter? he's got plenty of snails for company which were intended for food, but he has virtually no interest in them. are there other creatures i could consider adding, such as fish or crabs or something? i've taken walks through and around our marshes and lakes in my time, but i'm just not sure what would be a good idea.
