SCP-527 is a male humanoid, 1.67m in height, which is biologically non-anomalous, with the exception of its head, which is that of a Puntius semifasciolatus, or gold barb fish.
SCP-527 displays no other anomalous qualities. The head of SCP-527 functions the same as the head of any other non-anomalous human. SCP-527 is capable of typical human speech. A tattoo reading "Mr. Fish, from Little Misters ® by Dr. Wondertainment" appears on the bottom of its left foot.
