Purchased 2 along with 4 Dwarf otos to add to my 55 gallon. Its hard to find any behavior info on these as in do they need to be in a group or are they fine as loners like a Pleco. And do they eat the same algae as Dwarf Otos.
I believe they should be in groups as well, and I think their diet is similar to otos - provide veggies as well as algae and biofilm.

The fifth paragraph answers the question on being in groups.
