Slow growing stem plant with oval shaped leaves. The leaves are light green and with sufficient light the top leaves get a bit brown.

My experiences
I've had this plant in my aquarium for two times in the past. The first time I had this plant it grow pretty good and also had a bid brown tops, but after a few months I replaced them because they attracted to much algae. The second time I had this plant, the plants started losing their lower leaves after a short time and therefore I removed them from my aquarium. The lighting I used at these first two times was a 0.42 Watt/liter lumilux TL lighting.

At this time (21-10-01) I again have this plant in my aquarium since about five weeks. Because the lighting above my aquarium is stronger and the number of algae has decreased with time I hope this plant will do better this time. But the first three weeks it looked like that this plant again wouldn't do very well in my aquarium, because a number of plants attacked too much pointed algae and grew very slow. After three weeks I took the plants out of my aquarium to sort out the plants and replant only the stronger plants. Ones the plants were out of my aquarium I noticed that only the plants that had formed branches had attacked much pointed algae on them, while the plants without branches hardly had pointed algae on them. I suspect that the forming of branches took so much energy from the mother plant, that the pointed algae got a better change on these plants. Now two weeks after I replanted the stronger plants the group of Bacopa caroliniana in my aquarium is doing reasonable well and doesn't attrac much algae's at this time. 

Place and lighting in my aquarium
This plant stood in the mid-back and middle of my aquarium. The lighting I used for this plant varied between 0.42 Watt/liter standard TL lighting (2*18 Watt) till 0.63 Watt/liter standard TL lighting (3*18 Watt).
