Beth: Let me explain more clearly what I meant by attached to the glass...they do not accually attach themselves but rather when they drift to the glass of the aquarium by current and then since they are wet they kind of "stick" to the dry glass, by this I mean the current does not sweep them away since they are halfway in the water and half way out. Kind of hard to explain.
EelfreakRobi: I believe they do but if they were leeches i'd guess that they are the larvae of a leech since they do not move at all.
chinnyr: If one did fall into the tank it must have reproduced itself since if found 12 of these guys.
yellowfin: the pic was taken with my webcam. I will try shooting with my dig. camera...only problem is that it has a hard time focusing and getting detail on smaller oblects, but I will try.
thanks
Mike
