My clown knife lives in a sparcely furnished tank. It bores me, and I hope it dosent bore my knife. His main home in the tank is a large piece of PVC pipe that he loves in go in. Other than that there isnt really anything else in the tank except a very small clay pot which I has an airstone under (looks pretty cool when you hide the air tube.) I want to get fake plants for the tank and maybe some other decorations but I dont know what clown knife's would want? Anybody have a suggestion as to what I could put in the tank that wouldnt take up much swimming space for my knife but also loog good?
