Well I spent some time tonight researching rheophytic plants (plants that live between the low level and high level mark of fast moving streams, they are specialized to withstand the high current examples of other rheophytes that ppl would know are anubias and java fern) bucephalandras are all rheotypes and one thing I have read in a couple places is that during the rainy season when they are being submersed the most they enter a growth stage where they ae sending out shoots and during the dry season when they only get submersed sporatically they stop growing and focus on flowering. This may answer why you are seeing the shoots growing more while submersed. I'm not sure why root growth is more when emersed though.
