Those otocinclus can be viscious, hes probably killing all your fish while you sleep. Just kidding.

They are pretty cheap. You can get them at petco or petsmart. If its not that, then start looking at your loach, he probably recently started getting aggressive simply because hes getting too big for your tank and isn't being provided enough space anymore.

Should I get a larger hiding spot?

I think the loach is the problem. 10 gallons is far to small for a loach, and I'm sure hes gotten big. You need more like 125 gallons for an adult loach, so I doubt a hide is going to do much good as he gets larger and larger. Pretty soon hes going to be bigger than the tank anyways.
