Overview
Hygrophila Araguaia (Hygrophila lancea 'Araguaia') is a slow, compact stem plant with small bronze-red leaves, prized in scapes. It is a advanced plant to grow, and rewards a bit of experience and good light with a lovely display.
This guide explains, in plain language, how to grow Hygrophila Araguaia well: what it looks like, how much light it wants, whether it needs CO2, how to plant and place it, how to make more of it for free, and the simple mistakes to avoid.
Appearance & Growth
A slow, compact stem plant with small bronze-red leaves, prized in scapes.
It is a slow grower and is normally used in the midground of the aquarium. Because it grows slowly, it stays tidy and needs little trimming, though slow leaves can gather algae if the light is very strong.
Lighting
Hygrophila Araguaia does best under high light. It wants bright, even light reaching its leaves, so use a good planted-tank LED.
Keep the lights on a timer for about 6 to 8 hours a day. Leaving lights on longer usually grows more algae, not more plant, so add light time slowly and watch for any green film.
CO2 & Fertilising
CO2: Required. Added CO2 is really needed to grow this plant well and keep its colour and shape.
Feed it with an all-in-one liquid fertiliser (such as API Leaf Zone) each week. If leaves turn yellow, get holes, or stop growing, that is almost always a lack of nutrients, not a disease.
Planting & Placement
Plant Hygrophila Araguaia in the substrate, spacing stems or plants slightly apart so light and water reach them all. Root tabs in the substrate help it settle and grow strongly.
How to Propagate (Make More)
It is very easy to propagate: snip the top few centimetres off a healthy stem and push the cutting into the substrate. Each cut stem then branches and grows bushier.
Swapping cuttings is one of the best parts of the hobby - over time a single healthy plant can fill your tank and stock a few more.
Common Problems & How to Fix Them
The most common problem is algae growing on the leaves. This usually means too much light, not enough nutrients, or weak water flow - not a problem with the plant. Lower the light a little, add fertiliser, and improve flow.
Some leaf loss right after planting is normal while the plant gets used to living underwater - keep your light, CO2 and fertiliser steady and new growth will follow. Always remove dead or rotting leaves quickly to keep the plant and water healthy.
Is Hygrophila Araguaia Right for Your Tank?
Hygrophila Araguaia is a beautiful plant for keepers who can give it good light and CO2, well worth the small extra effort. Pair it with our other plant and aquascaping guides to build a lush, healthy planted tank.
