I have kept a number of species from the Rio Guaramo Iincluding nnanoluteus, and they have all been opportunistic omnivores.
When seasonally insects hatch out nanoluteus gorge on everything from larvae, to migrating termites, and their temporay wings,
at other more lean times, they survive on leaf litter and detritus.

The river is shallow in places where they are found, but fast flowing and collects a lot of leaf litter, tha makes up alot of the diet, with it comes hidden larvae.

Like HUKIT I place rocks outside in the sun to grow patches of algae for grazing, and they replaced as algae gets used up, and employ wave makers to simulaate natural riverine flow conditions
Some of the other species found with them are Chuco micropthamus, and Tomocichla asfaci.

Both are opportunistic omnivores, so for prepared foods, a diet of spirulina based pellets such as Algaemax, or foods created for marine reef dwellers that require high vegetarian content.
Even Panamanian Andinoacara from this area, if given the opportunity, will feast on algae.
