Rapashy Soilent Green is consumed with gusto by Ottos.
My thinking about feeding this is that they need nutrients that vegetables cannot supply and while a small number may be able to get this from the tank if you have a large number of Ottis they will rapidly exhaust the supply. Equally the jury seems to be out on their diet and some subspecies seem to be omniverous.
Hi @Onoma1
Recently, on another thread here on UKAPS, I mentioned that Otocinclus appear to consume periphyton, a cocktail of microflora and microfauna. For more information, take a look at:
https://en.wikipedia.org/wiki/Periphyton
My understanding is that Otocinclus will also eat brown 'algae' (diatoms). It's a fascinating world when you get down to the microscopic level.
