Lets hear how tall are the Bolbitus that you currently keep. If possible, please provide pictures of the entire plant, its leaf shape lying on a piece of white paper and changes you recall since you acquired it. Also helpful is the shade of green (some are very dark) to further help document the different versions. Finally, try to remember from who you obtained the plants to help establish the lineage. Tank conditions would be helpful, but I can't guess what the most important factors might be (KH&GH?). thx, Neil.

The Bolbitis that I currently keep gets to about 11" or so. I think it came originally from David Lim, which he sold as 'mini' Bolbitis. The reason I'm not certain is that I had another Bolbitis in one of my tanks that I had gotten from somebody else and they have gotten mixed somewhat. I seem to remember the Bolbitis I got from David was fuller towards the base of each frond and into the stem than what you see here. Maybe it's changed over time.

My Bolbitis is a light green, and KH and GH of tank is 90 ppm. This has been growing in a CO2 supplemented tank and 2.4 wpg of T5HO light.

Thanks David. Perfect response. The collective documentation from the APC will help us learn something new about this important plant. If you happen to know the pH (or CO2 concentration)that may also be helpful to describe the carbonate chemistry.

? I'm not David, David sold me the Bolbitis.

The pH of my tank is 6.02.
