In my opinion to be successful you will need to go more diverse in plant selection and need to select at least one live bearer and one easy egg layer. I would also keep MTS and probably a ramshell snail and some shrimp and select larger fish carefully. Diverse plant selection will allow good cover, control nutrients, and overall promote a healthy environment. For a filter I would leave most of it to the plants and just concentrate on good water movement. Lighting will depend on plant selection but I would keep it on the lower end and stay away from CO2
dosing and regiment regimes. Read up on Walstead tanks. Her book is a good read (minus some things she appears to force into her theory).
Tank mate selection will be critical. Guppies, endlers, and/or a platy would work to help create a food base. With lots of plants it will help protect some of fry to continue into adult hood. The plants will also help protect the shrimp in the same fashion if you select smaller species and will support snails as an additional food source. Larger Amanos can be kept and have little fear of being eaten by other fish based on selection but won't breed. Addition of larger "predatory" fish will typically strip the food base in short order and not leave you with a "mostly self sufficient" tank.
