Bene-FISH-al Extras Gammarus Refill

A pouch of EXTRA refill is able to fill the grinders twice.  Gammarus are a great protein source that are low in fat.  We recommend adding Gammarus to the Bene-FISH-al fish food before freezing but many fish will accept Gammarus directly and these can be used as a treat or a supplement by directly grinding some over the tank.
