my_sons_reef Posted August 22, 2016 Share Posted August 22, 2016 Just notice a TON of them on my rock work and glass. I've never seen them before at night. Are these Colonista snails? Sorry for the bad pics hard to clean them up on my phone Link to comment
Sancho Posted August 22, 2016 Share Posted August 22, 2016 They are not bad for any corals and graze all night long on the algae. The downside is that they are small enough to clog pumps which can suck. My sixline wrasse seems to peck at them and in my other tank I have a pistol shrimp that will pluck them off the wall. I let them be although they have stopped a pump and caused my ATO to stay on once. Link to comment
