Hellfire anemone for sale for ~$36...it's about 2.5 inches across and was thinking of adding it to my new pico built with all established live ocean rock. The only fish is a Greissenger Goby and he stays on the sandbed and searches the tunnels inside rocks for pods so i doubt he'd come in contact with it...but is this still a bad idea? There's not much flow from the HOB filter and although i could add a pump with suckers on it, worried that may be too much flow for the 2.5 gallon tank...thoughts?
