All the shrimp always have very dark stuff going through their digestive systems. Makes me wonder whether there was enough food in my last tank, or whether the algae is just different in this one and so looks darker once they eat it.
When I feed spirulina the poop gets dark. When I don't feed and they just eat regular algae it is light-colored. We've discussed it here. It could just mean that they now have a slightly different diet!? No worries I guess.

Ha! Please check out this post: SWIMMING BEHAVIOR and feel free to participate! You could also do the same with my questionnaire if you feel like it The Opae Ula Questionnaire
When I got my cylinder tank they used to race counterclockwise like crazy!!! This went on for some months. Now they don't do it that often anymore.
