I got my first Dwarf Orange Crayfish 3 weeks ago for our community tank. The first day or two, we saw him out and about exploring. Since then, I have only seen him about once a week. I think he hides during the day and comes out at night. I did see him eating alongside the mystery snail and one of my amano shrimp on some homemade snello one night after dark. Is this normal? Are they nocturnal and hide during the day? Or is it just scared until it gets bigger? I don't think anything is messing with it. I have a variety of small tetras, 2 female peacock gudgeons, corys, 1 Bolivian Ram who has never bothered anyone, some endlers, amano shrimp, mystery snail, nerite.
