I think plecos are an interesting fish, but should be owned with caution because they can eat the fish's slime coat, and they are messier than anything x.x Yes they clean, but CLEAN to us includes fecal matter, CLEAN for the fish includes him nomming on algae and wafers, and left over food. Not poop. No fish eats poop.
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
