Oh! not true! as far as lush plants go! you could totally use creeping Jenny! if comes in two colors and LOVEs humidity, and will even grow right into the water. it creates lots of little close leaves with good lighting and Ive used it in my riparium. Looks awesome so far though! Gah! all these cool ripariums to nothing but make me want to get more tanks! hehehe
Creeping Jenny is a great plant. Wish I could get a hold of some up here. I have tried ordering plants three times from folks on this site, but each time it has turned out to be a box of blackened mush. I guess thats the sacrifice for living amongst the bears and moose!
