My very first time in one of my local lfs,I said want spend £150 on starts of my cuc and for snails,I only want snails that can right themselves and mentioned ceriths as one of the snails I wanted as researched/ read they very beneficial,the owner of lfs went around putting cuc in bags and said £ 150 to much on first lot of cuc for a 3 month old tank and think ended up being £80.
He gave me nice selection of 2 urchins,2 conchs and sone nass snails and trouchus snails and about 10 hermits ( threw 1-2 extra of each apart from urchins,conchs but he said haven't put no ceriths in as he finds them very lazy so I just left at that,but after being on r2r around a year,I'm reading over and over again people say add them to help with certain algaes and to stir the samdbed up so after reading this thread, I think in next week or so will top up my cuc and get a handful of ceriths and decide for myself if lazy or beneficial myself,but the more variety the better imo aslong as we don't starve them ^_^
