I have a moderately planted 55 gallon tank with some, not much, brown algae.
I currently have two Otos and was wondering, if there is not enough algae
left for them to eat, what should I feed them?

The others have given you good advice. I doubt your otos will ever starve in a
tank that size. In fact, I would consider getting a couple more. Otos are at
their best in small groups, and you have room for them.

Most of my otos aren't interested in anything but algae. In my smaller tank,
which has no to algae to speak of, the otos sometimes eat the veggies I put in
for the snails. Zucchini slices (frozen, then thawed), peas, romaine lettuce,
apple slices, canned green beans. In my large tank, where there's more algae
and the otos are extremely fat, they are never interested in veggies.
