What is a Macrognathus eel?
A wonderful strip of fettuccine with a big ol’ bendy snout. These are the eels you want. The largest in the trade is M. aculeatus, sometimes called the lesser spiny eel, at 13" max. Keep in mind that this is a bendy piece of spaghetti. Its bioload and mass is approximately the same as a cichlid of half its length.
