Rereading Klaus Woltmans,"Exotic Aquarium Fishes." This is a very interesting looking fish! Does anyone have, or know about these guys. The picture is not so good and the information from my 1966 edition scant. I'm just curious.
They're best kept either singly or in large groups of 6 or more. Trying to keep 2 or a few will result in one becoming aggressive and causing injury to the other(s). With 6 or more the aggression is spread out sufficiently for them to co-exist.
