I have been trying to get my Ottocinclus feed on something apart from algae, but haven't had any success..
I've tried with Hikari Algae wafers, blanched cucumber, etc but the Ottos seem indifferent.
I have Amano shrimp, a hill stream loach and a couple guppies, all of them eat the food I dump in except for the Ottos.
I have even kept the food for over 24 hours but haven't seen a single Ottocinclus on it.
I do have a lot of green velvet algae on one side of glass and black algae( like a smooth mat covering anubias minima which I manually clean).
Would appreciate your thoughts and suggestions.
Thanks!
