I went to bed last night with 3 ghost shrimp in my tank, and this morning I woke up and couldnt find but 1, so 2 of them are missing. I dont know what happened to them, I put them in their about 3 days ago. I have looked everywhere, only thing I could think of is that the striped raphel ate them, but who knows, since they are clear and so tiny but I have looked all day to only find one. Any ideas?
