I bought this very small "opuntia quimilo" about a year ago, and it had no signs of pests or disease. Now, it is covered in dry, brown and tan crust. It's not root rot, as I don't overwater my cactus, and it is not sunburn, as it is an indoor cactus that gets light from a window. It seems to be eating away at the cactus, and spread to the new growth at the top. I have researched fungus, diseases, and scale insects, but I'm not convinced what it suffers from. What to I do? Can I save it? Help!

There aren't any slugs in the soil, and under a magnifying glass, there doesn't seem to be any bug larvae. Could it still be scale?

There is this one variety of scale thats quite large. Perhaps that one. Though IMC they favor monocots.
