Whats the difference?

[MANAMIES]

Can someone explain to me how to tell the difference between a catfish, a cory, and a pleco? How can you identify them by just looking at them?

all ducks are birds, but not all birds are ducks. corydoras are catfish. plecostomus are catfish. catfish are catfish. Google each and you'll see the difference in shape.

the three have different mouth shapes but all have barbels...
