Man you got a great deal I have 3 GN and paid 50$ for my big one. They are my favorite Pleco. They can be a little aggressive towards each other but I never have them damage each other. They can be very rewarding to watch with there beautiful color. Also they have 3 kinds from what I read. It depends on what part of the river they came from. Beginning,middle,end. There spot pattern will be large dots (less spots) and smaller dots (more spots) then there is very small dots (lots of spots ) this tells where at in the river the are from also I was told some can grow rather large 12" I have 2 GN that have similar spot patterns then I have 1GN that has large spot pattern he's also my biggest 5" curious to see how big each one grows in size compared to each other.
