If it is velvet methylene blue is not very effective, and with a catfish don't use a formalin/malachite green formulation either. Try Jungle Products Velvet Guard (a dimethylene based med) or some copper sulfate based med like Copper-safe or Aquarisol. Another fairly safe med (probably the safest with cats) is Acriflavine, this one is even safe on eggs and open wounds. All of these are available through BigAl'sOnline.
