1999, there were 2 large african tigerfish on display at Steinhart Aquarium, S.F., at first it was a very typical looking vittatus, about 2' long, later it died, and was replaced with another fish of the same lenght, but it had a noticeably shorter snout. Unfortunately I do not have pictures of them, but I use to go there every week and looked at them all the time, eventually both died. but I got to meet the senior curator there and got to know him after that.
