Otos can be bred in captivity, although it is not very common. Only
advice my books give is "they can be bred like Corydoras".

Well, there are about 20 Otocinclus species according to my books, and
Otocinclus affinis and O. arnoldi go best with that description.
Actually there is a possibility that it is a vestitus anyway and the
other oto is one of the other striped Otocinclus species.

Sounds like it is filled with eggs, but as you don't have a male for it,
you probably will not have any oto babies. I don't know if they can
crossbreed (I guess that they can), but if they do, don't sell the "mutts"
but keep them. You could also try to find a school of identical otos
(at least 4 more), condition them with good feeding and then try to
breed your fish.
