I am beginning to think Takashi Amano thrills to make me crazy. In his first book he had shrimp all over his tanks (Yamato Numaebi). In his two latest books, he has snails all over the place. The only snails I have felt safe keeping are Malaysian Trumpets. Clearly, Amano has a better idea. Does anyone have a guess as to what the snails in the tanks pictured in his latest books are? Makes me nuts! Justin Healy in sunny, dry, cool Savannah
