Unknown catfish

[Full3R]

Hey!
Recently i was looking at a Catfish available in a local pet store it measured about 20cm and there was smaller ones on sale of about 7cm
these fish were brown with white spots and a short body but a tall dorsal fin i was curious if anyone could possibly direct me to some pictures to find out the name of the fish
thanks!

The catfish could possibly be a Sailfish Pleco they grow to around 20cm

im not 100 percent positive you might be better going back to your lfs and asking them at least then you will get a correct answer
