ph 7.0
nitrate 50
nitrite 0

A bloated stomach is a classic sign of a disese called dropsy caused by an internal infection usually brought about from a lowered immune response as a reaction to stress.
It's very common to lose new fish in this way and otos seem more prone to it than some.

If your others avoid stress they should be spared, but it might be prudent to treat the tank with Interpet No9 anyway, just in case.
