i took some wood out from a water trough that i keep around for when i have the need to setup another tank and saw alot of those amphipod looking crustaceans. i managed to get the wood into a bucket and salvage some.i threw some into the frog tank and they went right to em.not enough time to even get a pic.i am wondering if there is a way to harvest these guys.its tought o not get the wood paricles in the tnaks with em.and i only see them in the very bottom of the nasty bin.anyhow tought it was kinda cool.
