Another great part of feeding earthworms (aside from their source of protein, and watching your bichirs death roll them), they are so easy to clean up when you're done. They don't dissolve into nasty gucky powder on the bottom of your tank like an uneaten pellet, or fall apart into chunks that are hard to get out. Sometimes fullsize worms can even survive underwater for a good long time (considering they are drowning) and when it IS time to get them out, just grab em

No mess clean up! Gotta love it!
