The cory habrosus is to small probably? I got those in my 30gallon.I think ropes was as an alternative. They aren’t active, but aren’t inactive either (like most polys I suppose). Personally I think the tank is too small for a fish like that anyway.
For the acaras you could do a school of tetras and also something like yo-yo loaches or Cory cats as bottom feeders.
Where does the blue acara come from in the wild?
