I have a 29 gal that is done cycling. I will have a dual 24 watt fixture putting out 48watts total (for those too lazy for math ) I want some type of plant to hide my filter tube, heater, and bubbler. I was thinking either thick jungle val or hornwort. Which would be better? I heard hornwort is a floating plant and can take over a tank easy. Is this true?? Im going to remove alot of gravel in the middle and move it to each side, making a river effect in the middle. Then small hills on each side. What are good easy plants? I do not want co2 or anything!
