Is your tank just newly established? Sounds like it is just brown algae (diatoms) that nearly all new tanks get and it usually goes away on its own once the tank/water chemistry has stabilised. It is very easy to ripe off. Checking the phosphate levels can be a good idea when algae problems arise.
Diatoms are one of the Oto's favourite food, but if your tank is newly setup I would suggest waiting at least 3-6 mths before adding the Oto's due to their sensitivity to water quality. I have never kept a planted tank so can't really comment, but having 0 readings across the board doesn't sound right, unless the plants are using up all the nitrates, you should have some level of nitrates showing.
If/when you do buy them, pick ones with nice round stomachs, shows they have been eating well. My Oto's also seem a lot more active since I turned the temperature down to 23* Celsius (instead of 25*), due to the Medakas preferring cooler temps., The oto's seem to prefer it too.
I have never kept plecos either, but thought they would need more space, but you may have plans for a bigger tank in the future.
