Overview
Echinodorus Red Diamond (Echinodorus 'Red Diamond') is a sword with deep wine-red, pointed leaves for a dramatic backdrop. It is a intermediate 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 Echinodorus Red Diamond 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 sword with deep wine-red, pointed leaves for a dramatic backdrop.
It is a medium grower and is normally used in the background 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
Echinodorus Red Diamond does best under medium to 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: Recommended. Adding CO2 gives the best growth and colour, but patient keepers can grow it more slowly without it.
Feed it with an all-in-one liquid fertiliser (such as API Leaf Zone) added to the water each week, and push a root tab into the substrate near the roots, as this is a hungry root-feeder. If leaves turn yellow, get holes, or stop growing, that is almost always a lack of nutrients, not a disease.
Planting & Placement
Plant Echinodorus Red Diamond in the substrate, spacing stems or plants slightly apart so light and water can reach them all. Root tabs in the substrate help it settle and grow strongly.
How to Propagate (Make More)
It makes baby plants on runners and flower stalks. Wait until each one has roots and a few leaves, then cut it free and plant it.
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 Echinodorus Red Diamond Right for Your Tank?
Echinodorus Red Diamond 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.
