Golds is in calgary, I am not sure if he has anymore as i picked up his last one (white calvu). He does how ever have some awesome wild caught gold head comps and zebra calvus (which look very close to the white calvus , that is the lighter ones of couse). Comps look very much like a calvus to the untrained eye someone would think they are but there not. They are however still part of the Altolamprolongus genus Take a look on golds site under their live stock section in the tanganikya part. they are in there. Awesome fish!
