cool i mean you really dont have alot to work with and i know you know that aye, but coolness for sure, i use escargot shells and some marine shells, if the syno is well fed you shouldnt really have too much of a problem but if you get tiny multi's or brevis even the juli's would snack on them, i agree with what you said about moving the rock work around so that one end is for the shellies and the juli's and the syno are at the other end maybe a divided line in the middle with rock work.. cool a photo would be sweet buddy, later..
