Has anyone got any tips on fan shrimp?I had two but one died after shedding. This remaining one is still very nervous after about five weeks. I know she comes out at night (after lights out I sneak looks in the tank and see her lurking behind moss balls etc. She spends most days in, or just poking out, of a natural cave in a large piece of bogwood, mostly hidden by plants, but sometimes I can see her fans waving about. I try and secretly syringe either frozen food (melted) or a pinch of fine fish food at her , very tricky as she will shoot back out of sight at the slightest thing, though she does not mind the dwarf corydoras now. Any advice?
