I wouldn't get otos until your tank has been set up for awhile. They can be pretty sensitive to newer tank setups and they need a good supply of algae. I have otos in my 46 and they seem to prefer the algae over the wafers.
i have had my tank up and running for about 4 months.
the tank is fully cycled, and i just got rid of the stock today to save room for the puffer.
but since i didnt get the puffer like the lfs said i would i will have to house a shubunky in my 10g until i get the puffer, where as the shubunky will go back into the pond with his friends.
BTW, plecos tend to grow pretty fast and even a bristle nose gets too large (4"-8" I believe) to comfortably house in a 10-gallon tank. They eat a lot, so they tend to poop quite a bit as well. I would not recommend a pleco of any type for a 10-gallon tank.
On the boards Otos are plecos in the common usage these days of any Loricariid, aka sucker-mouth catfish family, being labelled "pleco". But the Otos are as big as I would use also. A ten is too small for a bristlenose or even a Peckoltia and/or dwarf Panaque.
