I'll be watching for that. I've noticed that it is sending roots down into the substrate. It's probably getting ready to blast off. I think the 2 tiger lotus bulbs are gonna get huge as well. I will be moving some of this stuff to my 55g when I get it dirted. I'm hooked on dirt...LOL!
Banana plants became a PITA to me here being only a transition stage / form for the plant.
They eventually form a pond lily type of plant with surface leaves as they mature. Once it propagates surface leaves and roots the established plant losses the 'Banana'. They will rot and drop off has been my experience every time. Trimming off the roots and surface leaves will delay this but doesn't stop it.
The Fraternity of Dirt
If at first you don't succeed,,, keep kicking it RubberSideDownOnTheLanding, 2-75g planted, 5-55g planted, 5-20g planted, 110g w/30g sump, 8-10g, Refugium, doghouse/newbie 2012 update adding table top pleco pans & a 90g (Nutz)
Well, after 7 weeks, here is an update. I moved the pots around and added a different filter and some livestock (rcs, otos, and a red ramshorn snail) as a clean-up crew. The tiger lotus has really taken off. I've already had to trim the surface leaves twice to keep them from blocking all the light. Since the photos, I have removed one of the bulbs, split them up in pots, and placed in my 55g pfs only tank. What a mess that made! After a few wc's, it is mostly clean again. I apologize for my poor photography skills. I'm still working on that. The tank is super clear and not as yellow as the pics make it seem.
Thanks for looking! [img=http://img526.imageshack.us/img526/7056/20hdirttank008.th.jpg]
