killies or mummichogs for you northerners Any ol minnow trap w/ bread in a creek will catch all you need. Doritos also work especially well And they seem to survive fine in tap water and nasty eel water.
I dont keep nearly as many as 60 eels but more like 12 or so in a 20 gal filled half way w/ well water and an air pump,my tank cracked so I'am going to try a large storage bin as it is better then glass.
