I have been checking my tank out at night looking for pods. Unfortunately I do not think I have any yet but I have found something that I can not ID. They might be pods but they only come out on occasion not every night which I would assume the pods would. Cant really give a good description except that they come out once or twice a month (maybe more as I dont check the tank every night). They look white (at least in the red light I use) and are about a 1/8-1/4 long and thin (though they are getting bigger). They are never on the glass or rock but are always in the water column. They are always vertical and move by shimmying or wriggling. Hopefully someone will have an ID.
