I'm suprised noone has said smaller cichlids, speed is relative to size so a 6in fish traveling 4 feet in a second is more impressive than a 12in fish doing the same thing. I really don't see pbass as speedsters maybe because I've never had one and relate them to slow lunker large mouth bass from around here.
idk on chiclids but the fastest fish ive seen was a bone fish he sat there ,saw a fish about 50 yards away ,ate it and came back to the same place in about a second i think they would put up a heck of a fight on a rod and reel
