Agamyxis pectinifrons or Spotted Rafael, Talking Catfish Spotted Rafael Catfish are a peaceful animal. They are a solitary fish that will generally not bother other tank mates. They will do fine in a community tank, even if they are by themselves. The Spotted Rafael is nocturnal and will mostly hide during the day. I have one in with a Gar 5 Clown Loach a knife fish and a Arrow. and he is fine quite a nice looking fish and gets to about 7"
