So I looked up what Modest_Man said about the possibility that what we thought was a Jaguar Cichlid was actually a Wolf Cichlid.
Parachromis dovii ( Wolf Cichlid )
72 centimeters or 28 inches
Parachromis managuensis ( Jaguar Cichlid)
35 centimeters or 14 inches
I can't really tell them apart from a picture but the big difference between the two is that the Wolf gets twice as big as the Jaguar. One of these two foot or bigger Wolf Cichlids would probably go north of ten pounds.
Maybe "Pedro" the legend of Lake Wilson might actually be a wolf ?
