Most of my Otos are 1-2 years old.  I have at least two different 
species and none of them are over 1 1/2" long.  There may be 
species that grow _a little_ larger, but all of them can be 
considered small fish.

Well, again, they are small, but not quite _that_ small.  Adults 
average between 1 1/2-2", although occasionally they make it to 2 
1/2".  They were called Popondichthys furcata for years, but have 
been merged back into the genus Pseudomugil, and are now called 
Pseudomugil furcatus.  

In my experience, Pseudomugils make wonderful planted tank 
inhabitants if kept with other small peaceful fish.  With a 
sufficient amount of floating plants, you will find that you have 
a self-sustaining population.  They spawn readily, and the babies 
stay well hidden in the floaters.  They seem to find enough 
infusoria there to get off to a good start.  

I kept mine in my Discus tank, and the bright yellow flash of the 
Psuedomugils at the surface was a wonderful contrast to the blue 
Discus below.

Yes they are.
