Agressive Pleco

[CTlovesKS]

I have a tropical fish tank... 31.5 " length, 16" height, and 12" depth...

I did have 2 plecos and 2 catfish... My little catfish has dissapeared and no where to be found, and my rusty pleco keeps sucking on the sides of my clown pelco and my humbug catfish. I dont see why this is, because the 2 plecos came from the same tank before mine, and they got on fine there. Its well planted and I have a stack of rocks for hinding and a bogwood cave for them as well. Also a little coconut hut for them intill my fighter comes along. I dont see why the rusty is getting so agressive, can anyone help please.

The one that has turned agressive is about 4"
Clown plec is about 3"
and my humbug catfish is about 3/4 " too
