I saw a tank full of these in my lfs and they werent moving. Is it because they were sleeping as they are nocturnal or are they just like these always?
 
Great fish IMO. Very peaceful too. They don't move much lol, but when they do, they are very fast. Just try to keep them in odd numbered groups of 3 or more as they are happier in groups, and the odd numbers help prevent agression (spelling?).
