My Xingu was sick so I took it back to the LFS.... sniff..... He had a parasite and the store gave me one called a white pike in its place. I have no idea what species this is. I am thinking it might be an acutirostris, multispinosa, hemera, lucius, saxatilis, or a sveni. He has a long black stripe with verticle bars that are kind of faint, he has a spot on his caudal fin that is occelated and he has a humeral spot that is unocellated. He is 2-3" long and does not have any markings on his head save the stripe that runs the length of his body. He has maybe a triangular subocular marking but it is hard to tell. Any ideas?
