Well I have been running this 12 gallon nano for about 3 or 4 years now doing my water changes,keeping my parameters in check,Ph KH and salinty, my temp somtimes goes between 75.5 to 78 in the winter time,my only problem besides some nuisance algae, seams to be my snails they just dont last. I have some that have been in the tank for along time but I do go threw some tturbo's and cerith snails last night i saw my hermit crab and nauserous snails chowing down on a cerith and this morning my turbo is upside down I pushed him agnist the side but i bet when i come tonight he will be bait too..do other people have the same problem or do I have a critter in the tank thats snail tipping...
