Iam guessing a crayfish is the most agressive freshwater invertabrate am I wrong?

jUST WONDERING.
 
That'd be my guess, too! Although I would say they're more aggressive to each other. When fish are around they're just hungry.

Some crab species are more aggressive than any crayfish. Blue Crabs for example, are something god awfully evil and aggressive. Though, they're naturally a SW species, they can survive in BW and FW, so I'm using them as an example lol.

But some crays have a serious temper issue like you wouldn't believe. Oy!
