whats your humidity at.. i have some anubias that grows crazy in my viv.. i even found one in the soil no bigger than a fruit fly and i put it inbetween some rocks and its has a few leaves off it now..try getting your humidity up.
I have vents in the tank and a computer fan. The sides fog up quickly if I don't have the fan on. I just assume the humidity is too low because the anubias doesn't grow well out of water. The seem ok with it. They are azureus and stay out in the open all the time.
I never thought about Spathiphyllum. It may get too big though. Are there dwarf varieties?
Oh, woops. I DID bury all the roots! Damn. All this time...damn! I shouldn't have gotten rid of it then! I had taken it out of the gravel to get ready to ship it and left it floating freely for about a week and it did seem to be growing much better. And the leaves sticking out of the water looked fine. Oh well, live and learn. Thanks for lettin' me know.
Actually I think I'm already growing crypts. I got them as cuttings and put them in the substrate and they've been growing well. I thought they looked like water plants but the leaves were fairly stiff so I went ahead and put them directly in the soil. Maybe I'll get some more for the water section.
