I personally wouldn't put any Otos in a 5g. They are just 2 sensitive to water quality and small tanks can have problems alot quicker than larger ones. Plus a 5g just isn't enough room for a school of Otos to hang out and swim around. I see you already have 3 in there though.
Definitely don't add anymore. You have too many already IMO.
