yeah, they are similar to the common plecos but get a tad larger and have a larger dorsal fin, their common name is the sailfin pleco, i have a young one a little smaller than 4in and he is definitely not shy at all, he is out all the time and has no problem chasing the other fish away from his algae wafers, these are a mainly veggie pleco, and will eat mostly algae wafers and slices of zucchini, cucumber, etc that you put in there for them as well as the left over meaty pellets that get left over from your fish, but they get huge, like larger than 2ft!
