Ideas for a Creepy Aquarium

[Jayleth]

So I'm creating a cave based Halloween aquarium, but I'm having trouble finding creepy fish. I'm looking for small, creepy, freshwater fish and invertabrates. So far I've found blind cave tetras so I need fish that don't have long flowing fins or the tetras might bite them. I also have my eye on ghost shrimp. Another thing is this aquarium will have no lights and will be kept in my closet so I need fish that can tolerate that.
