Cabomba Growing Stretched Out

[rcalzadilla]

Why does my Cabomba Caroliniana grow all stretched out?
When I first received it was a lot bushier....the distance between leave was much less and the plant looked much better.

Like any other plant, Cabomba is going to grow better with good lighting, complete fertilizing, including CO2, and all three in sufficient amounts. My plants of various types generally get stringy when they are shaded too much by other plants, or are in a dark corner of the tank. Before I knew enough to use fertilizer and CO2 my plants were all stringy all the time. With the 1.6 watts per gallon I now use, a few of my higher light demand plants tend to be stringy near the bottom of the tank, but as they get closer to the light while growing, they get much fuller, better color, and they grow faster.
