i'm considering setting up a shrimp tank. any advice how should the layout be, the plants, the lights, hardscape? i've seen a iwagumi style tank, planted with only HC for shrimps. looks quite cool actually. but then there isnt any place for it to hide from the light. i'm not sure if it will breed in it my current tank has cardinal tetras. everytime i buy red cherries, they mysteriously disappear after a few days. must have ended up in the tetras, never hv any chance to breed.
