I recently got a chance to drop the project in a tank filled with West Coast rock Lobster at the local research aquarium during feeding time. The camera was set to do 15min videos overnight. 

Here is a timelapse made from the first 15min of footage:

Problems encountered:

• Low light (nothing I can do about that at this stage)
• Camera did not switch over to next flash drive after current one was full
• Focus was set too far forward to catch all the chaos right in front of it
