I messed with trying to tumble the eggs after reading Bret's article but did not make the soda pop tumbler. Since bandensis eggs are typically laid in the deepest, darkest, most hard to reach area (@cuttlegirl 's words but no one will dispute them) tumbling is likely not necessary for this species. I asked Bret if he had tried the soda bottle technique with bandensis and he confirmed success using it but also mentioned that other successful methods likely worked as well for the "stumpy" cuttles. Where the soda bottle incubator seems to have shown the most dramatic success has probably been with the flamboyants. The first page of my journal shares my incubator adventure (the first post has a link to the MBARI technique).
