If not is it maybe the tetras?
Replaced 4 corys with one oto and 2 honey gouramis yesterday and my god something in that tank can poop, ive had to sand vac twice today and if it wasnt so late id do it again now!
It has never been this quick to get messy and I can only guess its the oto as hes zooming all over the tank munching on stuff, Its good hes eating well but sheeeesh
if it can look this bad after 6 hours how bad is it going to be when I go away for 2-3days... 
I feed once aday (around 11am) and its a tiny pinch of flake for the 9 tetras and 3 gouris and about 1/3rd a sinking waffer for the Bolivian.
Did put abit of cucumber in for the oto in case the algae wasn't sufficient but he didnt touch it so took it out.
