I really like otocinclus, but I don't have a tank that produces enough algae for as many as I want. So, what do you feed them? I have tried algae disks and spirulina, but mine are uninterested.
I don't think so, i've had them for about a month. And when my 29 is fully cycled, I have to get about 6 of them. Are algae wafers the preferred choice then?
