Trochus Snails, Trochus sp.
1 introduced on the 10th November, 1 introduced on the 14th November 2016 & 1 introduced on the 27th December 2016. 2 more introduced on the 12th May 2017 and 2 on the 13th May 2017 bringing the current total of Trochus algae mowers to 7. Lost one of the newest Trochus on the 25th June (same supplier as the Ceriths, will not be buying any CUC from that shop again) so down to 6. I've added a few more over the years and probably lost a few too so really I've no idea how many I currently have. When I started the Reef-pro 1200 I introduced 11 Trochus over a 3 month period, then in July I discovered teeny tiny baby Trochus crawling about the sump and DT.
