This is a custom-designed anemone and fish guard that fits a Nero 5 wavemaker pump by Aquaillumination (Link to the pump & specs).
The guard is sleek and effective at protecting important livestock such as roaming anemones and small fish from getting suck into the Neer 5 impeller. Running a Neer 5 without a guard puts your tank's expensive livestock at risk. Even the stockfish guard that comes with the neer 5 is not effective at protecting your favorite little creatures.
