I have this plant in my tank with Seachem flourish and N ferts, DIY CO2 and 2 WPG and it is just flourishing. It is producing new stems all the time and growing several inches a week. I find it will grow different leaves depending on conditions- mine has round green leaves with blood red undersides, lancelot pink leaves and lancelot green leaves. It seems in the conditions mentioned the lancelot pink leaves seem most predominant.
I am a newbie when it comes to live aquatic plants. This plant did well in my small tank. The tank was only 9" tall but with a 15 w T8 bulb. It grew well and flourished. I used Excel Flourish and fertilizer tablets. I am now trying it out in a standard 10 gallon tank with two 15 watt bulbs. I hope it grows as nicely. These look best when planted in large patches.
This plant is very easy and grows quite fast. I've grown this in high light, without co2, with ferts and in Aqua Soil and inert gravel, but it grows faster in aquasoil. I've also grown it in an emersed tank. This is one of my favorite plant.
Despite its color, it is very forgiving for novice aquarists. A relatively fast grower that is comparable to many hygrophila species. An adaptable plant that can thrive in low tech conditions, but will absolutely flourish in high tech conditions.
