The Orange spotted behaviour is very different from the yellow-head. Yellow heads take a mouthful, then swim upward letting the sand fall through as they rise. Orange spotted stay on the sand bed. As a result, the yellow heads tend to deposit a lot more sand in higher areas.

However...like clockwork every few weeks, my orange spotted male tries to bury the female under a mountain of substrate. This is deliberate building not related to eating. Drives me nuts, but it is still easier than cleaning the sand all the time!
