Here is a pic of what I'm dealing with on my anubias and Amazon swords.
Can anyone let me know if this is due to the algae or something else?

Does it wipe right off? Looks like diatoms.

I havent tried to wipe it off. I suppose that should have been my first thought of something to do.

I thought it was discoloration of the actual leaf though, like a spot that was dieing.

When I get home from work i will try to wipe them and see if that helps. Also, if it is something that simply wipes off would that be something that a small group of Otos or another type of small bottom feeder would be able to keep clean and maintained?

I can't tell completely from the picture but it looks to me like it is on the leaf not part of the leaf. Ottos will eat diatoms.

Well, I brought home 4 Otocinclus cats today. I went out for dinner shortly after getting them in the tank. By the time I got back my anubias and amazon swords were all clean...no more brownish spots.

I've had similar looking spots on my plants (and gravel) sometimes. I've found that a good water change will usually make it go away. I think it's the remains of dead algae although I can't tell for sure. I usually try to wipe it off gently. Sometimes it works sometimes it doesn't.
