Thanks Todd, that's helpful info in a very concise list. When I bought my first clam no one told me they were difficult to keep in a newer tank. I've been lucky. After reading a book about them I realized I didn't even have what I thought... and I still forget and get them confused. Maybe a list of easy ways to ID would be a good addition to this thread? Once you know what to look for, Squamosa and Derasa are easy to tell apart. Crocea and Maxima, though, I still get mixed up.
