Are PVC loach caves more like tunnels that they can swim in one side and out the other or is one end blocked?
Are they best half buried in the substrate so that the floor of the cave is substrate, or pushed into the substrate and smooth PVC as the cave floor?
Does it matter how they are situated in the aquarium? (front, middle, back)
Does the inside need to be dark, ie: shadowed?
Any help greatly appreciated,
Thanks
