Its job in your tank: root feeder and midground plant.
A full-size sword look in a compact plant.
Harbich sword (Echinodorus ‘Harbich’, a compact form of E. cordifolius) grows broad, rounded leaves in a neat rosette about 6–12 inches tall. New leaves can come in with a bronze tint.
How it fits the Father Fish Method
Father Fish has kept fish for more than 70 years, and his method has helped thousands of aquarists build tanks that run on biology instead of bottles. A layer of living soil sits under a sand cap and feeds rooted plants for years. You plant heavily on day one and skip the CO2, liquid fertilizers and root tabs. Then the plants, the soil and the tiny life in them balance the tank. It’s a root feeder that settles.

Grew quickly in my 10-gallon tank with no CO2. The leaves are full and spread out nicely. I love how it looks like a full-sized sword but takes up less space. Works well with the living soil layer and doesn’t need any extra fertilizers.

It’s compact and fits perfectly in the midground. The bronze tint on new leaves is unique. I didn’t have to add any liquid fertilizers or root tabs. It’s a great fit for the Father Fish Method.

Planted it on day one with the living soil. After two months, it’s already 10 inches tall with a neat rosette. No CO2, no chemicals—just natural growth. Very satisfied with the results.
