Hey John, I purchased my CUC from you about a month ago. Everything is doing fine the macro algae didnt make it and a few snails and hermits have perished as expected but for the most part everything has survived and is doing great cleaning the tank. By the way I am pretty sure all the nice colors popping up in the tank are due to the million different colors of coralline algae that came in on the shells of the snails and hermits. My question is in regards to a growth on one of the Florida cerith shells. I can not get a picture because they are so small and I do not have the ability to take good macro shots so I will do my best to describe. They have a thin white stalk prob less then a half inch that stands erect. Then there are what looks almost like a feather duster at the end of that but the thin white/clear strands never go out and in they just stay out all the time. It is only on one shell but it is in rows going around the whole backside of the snail.
