Fish Feeding StationOther

EHEIM

Fish Feeding Station

The EHEIM feeding station serves the fish's meals underwater at a fixed location via a food chamber, so food can't drift far and everything is eaten; no decaying food residue contaminates the decorations or filter, and the water stays cleaner for longer. It consists of a food chamber and detachable platform designed as a base for the EHEIM autofeeder, turtlefeeder, and TWINfeeder, and the chamber can also be used as a defrosting station for frozen food cubes; suitable for fresh and marine water.
