Oh, I like that name ColloNistaaaaaaa...very Central America. Thank you. Now I can read about them.
Reading complete. Good snail. Reef friendly. High rate of reproduction. Tolerant of a huge variety of conditions. Slowed reproduction can be a sign of high nitrates. Do not let it clog piping, inlets, outlets, etc. A 'common' hitchhiker. First tank in which I have had this 'common' hitchhiker after using rock from three oceans and surely this came attached to an invertebrate or zoanthid frag within the last two years.
The way they line up in the corners by the filter box in the day is dress right dress military. As soon as the lights go dusk, they are out everywhere.
Thank you,
Mark
