In my 56g tank Ive got a group of Cabombas over in the back corner serving as my high point/equipment cover. Over time I have liked the plant less and less just because it seems to shed over time and since its been bushed up for so long, the lower portion of the plant is almost leafless. The growth rate of the plant is not an issue, I cut them back every week and its reallly a great plant for quick clipping transplants, but I would like to replace it with something that will grow at least 24" tall and stay very thick to cover the equipment in the rear. Just so no one has to ask, ive got 175 watts of MH light, injected C02 which would be right next to the new plant, flourite/eco-complete mix substrate, 78 degrees constant, 10 hour photoperiod, and dose ferts like theres no tomorrow. Any suggestions? Thick and tall, and I already have Red Ludwiga, Water Wisteria, Java Ferns, and Micro Swords (Narrow leaf). And a nice dark green or even some red would suit fine. Nothing bright green. Thanks in advance.
